-Garage is an S3-compatible distributed object storage service
+Garage is a lightweight S3-compatible distributed object store, with the following goals:
-designed for self-hosting at a small-to-medium scale.
 
-Garage is designed for storage clusters composed of nodes running
+- As self-contained as possible
-at different physical locations,
+- Easy to set up
-in order to easily provide a storage service that replicates data at these different
+- Highly resilient to network failures, network latency, disk failures, sysadmin failures
-locations and stays available even when some servers are unreachable.
+- Relatively simple
-Garage also focuses on being lightweight, easy to operate, and highly resilient to
+- Made for multi-datacenter deployments
-machine failures.
 
-Garage is built by [Deuxfleurs](https://deuxfleurs.fr),
+Non-goals include:
-an experimental small-scale self hosted service provider,
-which has been using it in production since its first release in 2020.
 
-Learn more on our dedicated documentation pages:
+- Extremely high performance
+- Complete implementation of the S3 API
+- Erasure coding (our replication model is simply to copy the data as is on several nodes, in different datacenters if possible)
 
-- [Goals and use cases](https://garagehq.deuxfleurs.fr/documentation/design/goals/)
+Our main use case is to provide a distributed storage layer for small-scale self hosted services such as [Deuxfleurs](https://deuxfleurs.fr).

-Garage has many API that you can rely on to build complex applications.
-In this section, we reference the existing SDKs and give some code examples.
-
-
-## ⚠️ DISCLAIMER
-
-**K2V AND ADMIN SDK ARE TECHNICAL PREVIEWS**. The following limitations apply:
-  - The API is not complete, some actions are possible only through the `garage` binary
-  - The underlying admin API is not yet stable nor complete, it can breaks at any time
-  - The generator configuration is currently tweaked, the library might break at any time due to a generator change
-  - Because the API and the library are not stable, none of them are published in a package manager (npm, pypi, etc.)
-  - This code has not been extensively tested, some things might not work (please report!)

-## About the APIs
-
-Code can interact with Garage through 3 different APIs: S3, K2V, and Admin.
-Each of them has a specific scope.
-
-### S3
-
-De-facto standard, introduced by Amazon, designed to store blobs of data.
-
-### K2V
-
-A simple database API similar to RiakKV or DynamoDB.
-Think a key value store with some additional operations.
-Its design is inspired by Distributed Hash Tables (DHT).
-
-More information:
-  - [In the reference manual](@/documentation/reference-manual/k2v.md)
-
-
-### Administration
-
-Garage operations can also be automated through a REST API.
-We are currently building this SDK for [Python](@/documentation/build/python.md#admin-api), [Javascript](@/documentation/build/javascript.md#administration) and [Golang](@/documentation/build/golang.md#administration).

-
-```bash
-pip3 install --user 'git+https://git.deuxfleurs.fr/garage-sdk/garage-admin-sdk-python'

-
-```python
-import garage_admin_sdk
-from garage_admin_sdk.apis import *
-from garage_admin_sdk.models import *
-
-configuration = garage_admin_sdk.Configuration(
-  host = "http://localhost:3903/v1",
-  access_token = "s3cr3t"
-)
-
-# Init APIs
-api = garage_admin_sdk.ApiClient(configuration)
-nodes, layout, keys, buckets = NodesApi(api), LayoutApi(api), KeyApi(api), BucketApi(api)
-
-# Display some info on the node
-status = nodes.get_nodes()
-print(f"running garage {status.garage_version}, node_id {status.node}")
-
-# Change layout of this node
-current = layout.get_layout()
-layout.add_layout([
-  NodeRoleChange(
-    id = status.node,
-    zone = "dc1",
-    capacity = 1000000000,
-    tags = [ "dev" ],
-  )
-])
-layout.apply_layout(LayoutVersion(
-  version = current.version + 1
-))
-
-# Create key, allow it to create buckets
-kinfo = keys.add_key(AddKeyRequest(name="openapi"))
-
-allow_create = UpdateKeyRequestAllow(create_bucket=True)
-keys.update_key(kinfo.access_key_id, UpdateKeyRequest(allow=allow_create))
-
-# Create a bucket, allow key, set quotas
-binfo = buckets.create_bucket(CreateBucketRequest(global_alias="documentation"))
-binfo = buckets.allow_bucket_key(AllowBucketKeyRequest(
-  bucket_id=binfo.id,
-  access_key_id=kinfo.access_key_id,
-  permissions=AllowBucketKeyRequestPermissions(read=True, write=True, owner=True),
-))
-binfo = buckets.update_bucket(binfo.id, UpdateBucketRequest(
-  quotas=UpdateBucketRequestQuotas(max_size=19029801,max_objects=1500)))
-
-# Display key
-print(f"""

-#### SSE-C encryption (since Garage v1.0)
-
-Since version 1.0, Garage supports server-side encryption with customer keys
-(SSE-C).  In this mode, Garage is responsible for encrypting and decrypting
-objects, but it does not store the encryption key itself. The encryption key
-should be provided by Nextcloud upon each request.  This mode of operation is
-supported by Nextcloud and it has successfully been tested together with
-Garage.
-
-To enable SSE-C encryption:
-
-1. Make sure your Garage server is accessible via SSL through a reverse proxy
-   such as Nginx, and that it is using a valid public certificate (Nextcloud
-   might be able to connect to an S3 server that is using a self-signed
-   certificate, but you will lose many hours while trying, so don't).
-   Configure values for `use_ssl` and `port` accordingly in your `config.php`
-   file.
-
-2. Generate an encryption key using the following command:
-
-    ```
-    openssl rand -base64 32
-    ```
-
-    Make sure to keep this key **secret**!
-
-3. Add the encryption key in your `config.php` file as follows:
-
-
-    ```php
-    <?php
-    $CONFIG = array(
-    'objectstore' => [
-        'class' => '\\OC\\Files\\ObjectStore\\S3',
-        'arguments' => [
-            ...
-            'sse_c_key' => 'exampleencryptionkeyLbU+5fKYQcVoqnn+RaIOXgo=',
-            ...
-        ],
-    ],
-    ```
-
-Nextcloud will now make Garage encrypt files at rest in the storage bucket.
-These files will not be readable by an S3 client that has credentials to the
-bucket but doesn't also know the secret encryption key.
-
-

 We show how it is still possible to configure Garage with Peertube, allowing you to spread the load and the bandwidth usage on the Garage cluster.
 
-Starting from version 5.0, Peertube also supports improving the security for private videos by not exposing them directly
-but relying on a single control point in the Peertube instance. This is based on S3 per-object and prefix ACL, which are not currently supported

 ## Mastodon
 
-Mastodon natively supports the S3 protocol to store media files, and it works out-of-the-box with Garage.
+https://docs.joinmastodon.org/admin/config/#cdn
-You will need to expose your Garage bucket as a website: that way, media files will be served directly from Garage.
-
-### Performance considerations
-
-Mastodon tends to store many small objects over time: expect hundreds of thousands of objects,
-with average object size ranging from 50 KB to 150 KB.
-
-As such, your Garage cluster should be configured appropriately for good performance:
-
-- use Garage v0.8.0 or higher with the [LMDB database engine](@documentation/reference-manual/configuration.md#db-engine-since-v0-8-0).
-  Older versions of Garage used the Sled database engine which had issues, such as databases quickly ending up taking tens of GB of disk space.
-- the Garage database should be stored on a SSD
-
-### Creating your bucket
-
-This is the usual Garage setup:
-
-```bash
-garage key create mastodon-key
-garage bucket create mastodon-data
-garage bucket allow mastodon-data --read --write --key mastodon-key
-```
-
-Note the Key ID and Secret Key.
-
-### Exposing your bucket as a website
-
-Create a DNS name to serve your media files, such as `my-social-media.mydomain.tld`.
-This name will be publicly exposed to the users of your Mastodon instance: they
-will load images directly from this DNS name.
-
-As [documented here](@/documentation/cookbook/exposing-websites.md),
-add this DNS name as alias to your bucket, and expose it as a website:
-
-```bash
-garage bucket alias mastodon-data my-social-media.mydomain.tld
-garage bucket website --allow mastodon-data
-```
-
-Then you will likely need to [setup a reverse proxy](@/documentation/cookbook/reverse-proxy.md)
-in front of it to serve your media files over HTTPS.
-
-### Cleaning up old media files before migration
-
-Mastodon instance quickly accumulate a lot of media files from the federation.
-Most of them are not strictly necessary because they can be fetched again from
-other servers.  As such, it is highly recommended to clean them up before
-migration, this will greatly reduce the migration time.

-### Migrating your data
-
-Data migration should be done with an efficient S3 client.
-The [minio client](@documentation/connect/cli.md#minio-client) is a good choice
-thanks to its mirror mode:
-
-```bash
-mc mirror ./public/system/ garage/mastodon-data
-```
-
-Here is a typical bucket usage after all data has been migrated:
-
-```bash
-$ garage bucket info mastodon-data
-
-Size: 20.3 GiB (21.8 GB)
-Objects: 175968
-```
-
-### Configuring Mastodon
-
-In your `.env.production` configuration file:
-
-```bash
-S3_ENABLED=true
-# Internal access to Garage
-S3_ENDPOINT=http://my-garage-instance.mydomain.tld:3900
-S3_REGION=garage
-S3_BUCKET=mastodon-data
-# Change this (Key ID and Secret Key of your Garage key)
-AWS_ACCESS_KEY_ID=GKe88df__CHANGETHIS__c5145
-AWS_SECRET_ACCESS_KEY=a2f7__CHANGETHIS__77fcfcf7a58f47a4aa4431f2e675c56da37821a1070000
-# What name gets exposed to users (HTTPS is implicit)
-S3_ALIAS_HOST=my-social-media.mydomain.tld
-```
-
-For more details, see the [reference Mastodon documentation](https://docs.joinmastodon.org/admin/config/#cdn).
-
-Restart all Mastodon services and everything should now be using Garage!
-You can check the URLs of images in the Mastodon web client, they should start
-with `https://my-social-media.mydomain.tld`.
-
-### Last migration sync
-
-After Mastodon is successfully using Garage, you can run a last sync from the local filesystem to Garage:
-
-```bash
-mc mirror --newer-than "3h" ./public/system/ garage/mastodon-data
-```

-module in the [ejabberd-contrib](https://github.com/processone/ejabberd-contrib)
-repository, can be integrated to store chat media files in Garage.
-

-through the [static website](@/documentation/cookbook/exposing-websites.md)
-functionality.
-
-As the data itself is publicly accessible to someone with knowledge of the

-[E2EE](@/documentation/cookbook/encryption.md) to protect this data-at-rest
-from unauthorized access.
-
-Install the module with:
-
-```bash

-```
-
-Create the required key and bucket with:

+Lemmy uses pict-rs that [supports S3 backends](https://git.asonix.dog/asonix/pict-rs/commit/f9f4fc63d670f357c93f24147c2ee3e1278e2d97)
-This feature requires `pict-rs >= 4.0.0`.
-
-### Creating your bucket
-
-This is the usual Garage setup:
-
-```bash
-garage key new --name pictrs-key
-garage bucket create pictrs-data
-garage bucket allow pictrs-data --read --write --key pictrs-key
-```
-
-Note the Key ID and Secret Key.
-
-### Migrating your data
-
-If your pict-rs instance holds existing data, you first need to migrate to the S3 bucket.
-
-Stop pict-rs, then run the migration utility from local filesystem to the bucket:
-
-```
-pict-rs \
-  filesystem -p /path/to/existing/files \
-  object-store \
-   -e my-garage-instance.mydomain.tld:3900 \
-   -b pictrs-data \

-   -a GK... \
-   -s abcdef0123456789...
-```
-
-This is pretty slow, so hold on while migrating.
-
-### Running pict-rs with an S3 backend
-
-Pict-rs supports both a configuration file and environment variables.
-
-Either set the following section in your `pict-rs.toml`:
-
-```
-[store]

-endpoint = 'http://my-garage-instance.mydomain.tld:3900'

-echo "Generated password (save it safely): $(openssl rand -base64 32)"
-export RESTIC_PASSWORD=xxx # copy paste your generated password here

-
-Do not forget to save your password safely (in your password manager or print it). It will be needed to decrypt your backups.
-
-Now you can use restic:
-
-```bash
-# Initialize the bucket, must be run once
-restic init
-
-# Backup your PostgreSQL database
-# (We suppose your PostgreSQL daemon is stopped for all commands)
-restic backup /var/lib/postgresql

-encryption practices and things like key management, as we want Garage to be a
-serious base platform for the developpment of secure, encrypted applications.
-Do not hesitate to come talk to us if you have any thoughts or questions on the
-subject.
-
-
-# Capabilities provided by Garage
-
-## Traffic is encrypted between Garage nodes
-
-RPCs between Garage nodes are encrypted. More specifically, contrary to many
-distributed software, it is impossible in Garage to have clear-text RPC.  We
-use the [kuska handshake](https://github.com/Kuska-ssb/handshake) library which
-implements a protocol that has been clearly reviewed, Secure ScuttleButt's
-Secret Handshake protocol.  This is why setting a `rpc_secret` is mandatory,
-and that's also why your nodes have super long identifiers.
-
-## HTTP API endpoints provided by Garage are in clear text
-
-Adding TLS support built into Garage is not currently planned.
-
-## Garage stores data in plain text on the filesystem or encrypted using customer keys (SSE-C)
-
-For standard S3 API requests, Garage does not encrypt data at rest by itself.
-For the most generic at rest encryption of data, we recommend setting up your
-storage partitions on encrypted LUKS devices.
-
-If you are developping your own client software that makes use of S3 storage,
-we recommend implementing data encryption directly on the client side and never
-transmitting plaintext data to Garage. This makes it easy to use an external
-untrusted storage provider if necessary.
-
-Garage does support [SSE-C
-encryption](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ServerSideEncryptionCustomerKeys.html),
-an encryption mode of Amazon S3 where data is encrypted at rest using
-encryption keys given by the client.  The encryption keys are passed to the
-server in a header in each request, to encrypt or decrypt data at the moment of
-reading or writing. The server discards the key as soon as it has finished
-using it for the request.  This mode allows the data to be encrypted at rest by
-Garage itself, but it requires support in the client software. It is also not
-adapted to a model where the server is not trusted or assumed to be
-compromised, as the server can easily know the encryption keys.  Note however
-that when using SSE-C encryption, the only Garage node that knows the
-encryption key passed in a given request is the node to which the request is
-directed (which can be a gateway node), so it is easy to have untrusted nodes
-in the cluster as long as S3 API requests containing SSE-C encryption keys are
-not directed to them.
-
-Implementing automatic data encryption directly in Garage without client-side
-management of keys (something like
-[SSE-S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingServerSideEncryption.html))
-could make things simpler for end users that don't want to setup LUKS, but also
-raises many more questions, especially around key management: for encryption of
-data, where could Garage get the encryption keys from? If we encrypt data but
-keep the keys in a plaintext file next to them, it's useless. We probably don't
-want to have to manage secrets in Garage as it would be very hard to do in a
-secure way. At the time of speaking, there are no plans to implement this in
-Garage.
-
-
-# Adding data encryption using external tools
-
-## Encrypting traffic between a Garage node and your client
-
-You have multiple options to have encryption between your client and a node:
-
-  - Setup a reverse proxy with TLS / ACME / Let's encrypt
-  - Setup a Garage gateway locally, and only contact the garage daemon on `localhost`
-  - Only contact your Garage daemon over a secure, encrypted overlay network such as Wireguard
-
-## Encrypting data at rest
-
-Protects against the following threats:
-
-- Stolen HDD
-
-Crucially, does not protect againt malicious sysadmins or remote attackers that
-might gain access to your servers.
-
-Methods include full-disk encryption with tools such as LUKS.
-
-## Encrypting data on the client side
-
-Protects againt the following threats:
-
-- A honest-but-curious administrator
-- A malicious administrator that tries to corrupt your data
-- A remote attacker that can read your server's data
-
-Implementations are very specific to the various applications. Examples:
-
-- Matrix: uses the OLM protocol for E2EE of user messages. Media files stored
-  in Matrix are probably encrypted using symmetric encryption, with a key that is
-  distributed in the end-to-end encrypted message that contains the link to the object.
-
-- XMPP: clients normally support either OMEMO / OpenPGP for the E2EE of user
-  messages. Media files are encrypted per
-  [XEP-0454](https://xmpp.org/extensions/xep-0454.html).
-
-- Aerogramme: use the user's password as a key to decrypt data in the user's bucket
-
-- Cyberduck: comes with support for
-  [Cryptomator](https://docs.cyberduck.io/cryptomator/) which allows users to
-  create client-side vaults to encrypt files in before they are uploaded to a
-  cloud storage endpoint.

-Garage exposes some internal metrics in the Prometheus data format.
-This page explains how to exploit these metrics.
-
-## Setting up monitoring
-
-### Enabling the Admin API endpoint
-
-If you have not already enabled the [administration API endpoint](@/documentation/reference-manual/admin-api.md), do so by adding the following lines to your configuration file:
-
-```toml
-[admin]
-api_bind_addr = "0.0.0.0:3903"
-```
-
-This will allow anyone to scrape Prometheus metrics by fetching
-`http://localhost:3903/metrics`. If you want to restrict access
-to the exported metrics, set the `metrics_token` configuration value
-to a bearer token to be used when fetching the metrics endpoint.
-
-### Setting up Prometheus and Grafana
-
-Add a scrape config to your Prometheus daemon to scrape metrics from
-all of your nodes:
-
-```yaml
-scrape_configs:
-  - job_name: 'garage'
-    static_configs:
-      - targets:
-        - 'node1.mycluster:3903'
-        - 'node2.mycluster:3903'
-        - 'node3.mycluster:3903'
-```
-
-If you have set a metrics token in your Garage configuration file,
-add the following lines in your Prometheus scrape config:
-
-```yaml
-    authorization:
-      type: Bearer
-      credentials: 'your metrics token'
-```
-
-To visualize the scraped data in Grafana,
-you can either import our [Grafana dashboard for Garage](https://git.deuxfleurs.fr/Deuxfleurs/garage/raw/branch/main/script/telemetry/grafana-garage-dashboard-prometheus.json)
-or make your own.

 To run a real-world deployment, make sure the following conditions are met:
 
 - You have at least three machines with sufficient storage space available.

-  [Nebula](https://github.com/slackhq/nebula) or
-  [Yggdrasil](https://yggdrasil-network.github.io/) are approaches to consider
-  in addition to building out your own VPN tunneling.
 
-- This guide will assume you are using Docker containers to deploy Garage on each node.

-Note that Garage will **always** store the three copies of your data on nodes at different
-locations. This means that in the case of this small example, the usable capacity
-of the cluster is in fact only 1.5 TB, because nodes in Brussels can't store more than that.
-This also means that nodes in Paris and London will be under-utilized.
-To make better use of the available hardware, you should ensure that the capacity
-available in the different locations of your cluster is roughly the same.
-For instance, here, the Mercury node could be moved to Brussels; this would allow the cluster
-to store 2 TB of data in total.
 
-### Best practices
-
-- If you have reasonably fast networking between all your nodes, and are planing to store
-  mostly large files, bump the `block_size` configuration parameter to 10 MB
-  (`block_size = "10M"`).
-
-- Garage stores its files in two locations: it uses a metadata directory to store frequently-accessed
-  small metadata items, and a data directory to store data blocks of uploaded objects.
-  Ideally, the metadata directory would be stored on an SSD (smaller but faster),
-  and the data directory would be stored on an HDD (larger but slower).
-
-- For the data directory, Garage already does checksumming and integrity verification,
-  so there is no need to use a filesystem such as BTRFS or ZFS that does it.
-  We recommend using XFS for the data partition, as it has the best performance.
-  EXT4 is not recommended as it has more strict limitations on the number of inodes,
-  which might cause issues with Garage when large numbers of objects are stored.
-
-- Servers with multiple HDDs are supported natively by Garage without resorting
-  to RAID, see [our dedicated documentation page](@/documentation/operations/multi-hdd.md).
-
-- For the metadata storage, Garage does not do checksumming and integrity
-  verification on its own, so it is better to use a robust filesystem such as
-  BTRFS or ZFS. Users have reported that when using the LMDB database engine
-  (the default), database files have a tendency of becoming corrupted after an
-  unclean shutdown (e.g. a power outage), so you should take regular snapshots
-  to be able to recover from such a situation.  This can be done using Garage's
-  built-in automatic snapshotting (since v0.9.4), or by using filesystem level
-  snapshots. If you cannot do so, you might want to switch to Sqlite which is
-  more robust.
-
-- LMDB is the fastest and most tested database engine, but it has the following
-  weaknesses: 1/ data files are not architecture-independent, you cannot simply
-  move a Garage metadata directory between nodes running different architectures,
-  and 2/ LMDB is not suited for 32-bit platforms. Sqlite is a viable alternative
-  if any of these are of concern.
-
-- If you only have an HDD and no SSD, it's fine to put your metadata alongside
-  the data on the same drive, but then consider your filesystem choice wisely
-  (see above). Having lots of RAM for your kernel to cache the metadata will
-  help a lot with performance.  The default LMDB database engine is the most
-  tested and has good performance.

-## Replacement scenario 3: corrupted metadata {#corrupted_meta}
-
-In some cases, your metadata DB file might become corrupted, for instance if
-your node suffered a power outage and did not shut down properly. In this case,
-you can recover without having to change the node ID and rebuilding a cluster
-layout. This means that data blocks will not need to be shuffled around, you
-must simply find a way to repair the metadata file. The best way is generally
-to discard the corrupted file and recover it from another source.
-
-First of all, start by locating the database file in your metadata directory,
-which [depends on your `db_engine`
-choice](@/documentation/reference-manual/configuration.md#db_engine).  Then,
-your recovery options are as follows:
-
-- **Option 1: resyncing from other nodes.** In case your cluster is replicated
-  with two or three copies, you can simply delete the database file, and Garage
-  will resync from other nodes. To do so, stop Garage, delete the database file
-  or directory, and restart Garage. Then, do a full table repair by calling
-  `garage repair -a --yes tables`.  This will take a bit of time to complete as
-  the new node will need to receive copies of the metadata tables from the
-  network.
-
-- **Option 2: restoring a snapshot taken by Garage.** Since v0.9.4, Garage can
-  [automatically take regular
-  snapshots](@/documentation/reference-manual/configuration.md#metadata_auto_snapshot_interval)
-  of your metadata DB file. This file or directory should be located under
-  `<metadata_dir>/snapshots`, and is named according to the UTC time at which it
-  was taken. Stop Garage, discard the database file/directory and replace it by the
-  snapshot you want to use. For instance, in the case of LMDB:
-
-  ```bash
-  cd $METADATA_DIR
-  mv db.lmdb db.lmdb.bak
-  cp -r snapshots/2024-03-15T12:13:52Z db.lmdb
-  ```
-
-  And for Sqlite:
-
-  ```bash
-  cd $METADATA_DIR
-  mv db.sqlite db.sqlite.bak
-  cp snapshots/2024-03-15T12:13:52Z db.sqlite
-  ```
-
-  Then, restart Garage and run a full table repair by calling `garage repair -a
-  --yes tables`.  This should run relatively fast as only the changes that
-  occurred since the snapshot was taken will need to be resynchronized. Of
-  course, if your cluster is not replicated, you will lose all changes that
-  occurred since the snapshot was taken.
-
-- **Option 3: restoring a filesystem-level snapshot.** If you are using ZFS or
-  BTRFS to snapshot your metadata partition, refer to their specific
-  documentation on rolling back or copying files from an old snapshot.

-  [http.routers.my_website]
-    rule = "Host(`yoururl.example.org`)"
-    service = "garage-web-service"
-    entryPoints = ["websecure"]
-```
-
-Enable HTTPS access to your website with the following configuration section ([documentation](https://doc.traefik.io/traefik/https/overview/)):
-
-```toml
-...
-    entryPoints = ["websecure"]

-## Caddy
-
-Your Caddy configuration can be as simple as:
-
-```caddy
-s3.garage.tld, *.s3.garage.tld {
-	reverse_proxy localhost:3900 192.168.1.2:3900 example.tld:3900 {
-        health_uri       /health
-        health_port      3903
-        #health_interval 15s
-        #health_timeout  5s
-    }
-}
-
-*.web.garage.tld {
-	reverse_proxy localhost:3902 192.168.1.2:3902 example.tld:3902 {
-        health_uri       /health
-        health_port      3903
-        #health_interval 15s
-        #health_timeout  5s
-    }
-}
-
-admin.garage.tld {
-	reverse_proxy localhost:3903 {
-        health_uri       /health
-        health_port      3903
-        #health_interval 15s
-        #health_timeout  5s
-    }
-}
-```
-
-But at the same time, the `reverse_proxy` is very flexible.
-For a production deployment, you should [read its documentation](https://caddyserver.com/docs/caddyfile/directives/reverse_proxy) as it supports features like DNS discovery of upstreams, load balancing with checks, streaming parameters, etc.
-
-### Caching
-
-Caddy can compiled with a
-[cache plugin](https://github.com/caddyserver/cache-handler) which can be used
-to provide a hot-cache at the webserver-level for static websites hosted by
-Garage.
-
-This can be configured as follows:
-
-```caddy
-# Caddy global configuration section
-{
-	# Bare minimum configuration to enable cache.
-	order cache before rewrite
-
-	cache
-
-	#cache
-	#	allowed_http_verbs GET
-	#	default_cache_control public
-	#	ttl 8h
-	#}
-}
-
-# Site specific section
-https:// {
-	cache
-
-	#cache {
-	#	timeout {
-	#		backend 30s
-	#	}
-	#}
-
-	reverse_proxy ...
-}
-```
-
-Caching is a complicated subject, and the reader is encouraged to study the
-available options provided by the plugin.
-
-### On-demand TLS
-
-Caddy supports a technique called
-[on-demand TLS](https://caddyserver.com/docs/automatic-https#on-demand-tls), by
-which one can configure the webserver to provision TLS certificates when a
-client first connects to it.
-
-In order to prevent an attack vector whereby domains are simply pointed at your
-webserver and certificates are requested for them - Caddy can be configured to
-ask Garage if a domain is authorized for web hosting, before it then requests
-a TLS certificate.
-
-This 'check' endpoint, which is on the admin port (3903 by default), can be
-configured in Caddy's global section as follows:
-
-```caddy
-{
-	...
-	on_demand_tls {
-		ask http://localhost:3903/check
-		interval 2m
-		burst 5
-	}
-	...
-}
-```
-
-The host section can then be configured with (note that this uses the web
-endpoint instead):
-
-```caddy
-# For a specific set of subdomains
-*.web.garage.tld {
-	tls {
-		on_demand
-	}
-
-	reverse_proxy localhost:3902 192.168.1.2:3902 example.tld:3902
-}
-
-# Accept all domains on HTTPS
-# Never configure this without global section above
-https:// {
-	tls {
-		on_demand
-	}
-
-	reverse_proxy localhost:3902 192.168.1.2:3902 example.tld:3902
-}
-```
-
-More information on how this endpoint is implemented in Garage is available
-in the [Admin API Reference](@/documentation/reference-manual/admin-api.md) page.
-
-### Fileserver browser
-
-Caddy's built-in
-[file_server](https://caddyserver.com/docs/caddyfile/directives/file_server)
-browser functionality can be extended with the
-[caddy-fs-s3](https://github.com/sagikazarmark/caddy-fs-s3) module.
-
-This can be configured to use Garage as a backend with the following
-configuration:
-
-```caddy
-browse.garage.tld {
-    file_server {
-        fs s3 {
-            bucket test-bucket
-            region garage
-
-            endpoint https://s3.garage.tld
-            use_path_style
-        }
-
-        browse
-    }
-}
-```
-
-Caddy must also be configured with the required `AWS_ACCESS_KEY_ID` and
-`AWS_SECRET_ACCESS_KEY` environment variables to access the bucket.

-## Request routing logic
-
-Data retrieval requests to Garage endpoints (S3 API and websites) are resolved 
-to an individual object in a bucket. Since objects are replicated to multiple nodes 
-Garage must ensure consistency before answering the request.
-
-### Using quorum to ensure consistency
-
-Garage ensures consistency by attempting to establish a quorum with the
-data nodes responsible for the object. When a majority of the data nodes
-have provided metadata on a object Garage can then answer the request.
-
-When a request arrives Garage will, assuming the recommended 3 replicas, perform the following actions:
-
-- Make a request to the two preferred nodes for object metadata
-- Try the third node if one of the two initial requests fail
-- Check that the metadata from at least 2 nodes match
-- Check that the object hasn't been marked deleted
-- Answer the request with inline data from metadata if object is small enough
-- Or get data blocks from the preferred nodes and answer using the assembled object
-
-Garage dynamically determines which nodes to query based on health, preference, and 
-which nodes actually host a given data. Garage has no concept of "primary" so any 
-healthy node with the data can be used as long as a quorum is reached for the metadata.
-
-### Node health
-
-Garage keeps a TCP session open to each node in the cluster and periodically pings them. If a connection
-cannot be established, or a node fails to answer a number of pings, the target node is marked as failed.
-Failed nodes are not used for quorum or other internal requests.
-
-### Node preference
-
-Garage prioritizes which nodes to query according to a few criteria:
-
-- A node always prefers itself if it can answer the request
-- Then the node prioritizes nodes in the same zone
-- Finally the nodes with the lowest latency are prioritized 
-

-
-To ensure the best durability of your data and to fix any inconsistencies that may
-pop up in a distributed system, Garage provides a series of repair operations.
-This guide will explain the meaning of each of them and when they should be applied.
-
-
-# General syntax of repair operations
-
-Repair operations described below are of the form `garage repair <repair_name>`.
-These repairs will not launch without the `--yes` flag, which should
-be added as follows: `garage repair --yes <repair_name>`.
-By default these repair procedures will only run on the Garage node your CLI is
-connecting to. To run on all nodes, add the `-a` flag as follows:
-`garage repair -a --yes <repair_name>`.
-
-# Data block operations
-
-## Data store scrub {#scrub}
-
-Scrubbing the data store means examining each individual data block to check that
-their content is correct, by verifying their hash. Any block found to be corrupted
-(e.g. by bitrot or by an accidental manipulation of the datastore) will be
-restored from another node that holds a valid copy.
-
-Scrubs are automatically scheduled by Garage to run every 25-35 days (the
-actual time is randomized to spread load across nodes). The next scheduled run
-can be viewed with `garage worker get`.
-
-A scrub can also be launched manually using `garage repair scrub start`.
-
-To view the status of an ongoing scrub, first find the task ID of the scrub worker
-using `garage worker list`. Then, run `garage worker info <scrub_task_id>` to
-view detailed runtime statistics of the scrub. To gather cluster-wide information,
-this command has to be run on each individual node.
-
-A scrub is a very disk-intensive operation that might slow down your cluster.
-You may pause an ongoing scrub using `garage repair scrub pause`, but note that
-the scrub will resume automatically 24 hours later as Garage will not let your
-cluster run without a regular scrub. If the scrub procedure is too intensive
-for your servers and is slowing down your workload, the recommended solution
-is to increase the "scrub tranquility" using `garage repair scrub set-tranquility`.
-A higher tranquility value will make Garage take longer pauses between two block
-verifications. Of course, scrubbing the entire data store will also take longer.
-
-## Block check and resync
-
-In some cases, nodes hold a reference to a block but do not actually have the block
-stored on disk. Conversely, they may also have on-disk blocks that are not referenced
-any more. To fix both cases, a block repair may be run with `garage repair blocks`.
-This will scan the entire block reference counter table to check that the blocks
-exist on disk, and will scan the entire disk store to check that stored blocks
-are referenced.
-
-It is recommended to run this procedure when changing your cluster layout,
-after the metadata tables have finished synchronizing between nodes
-(usually a few hours after `garage layout apply`).
-
-## Inspecting lost blocks
-
-In extremely rare situations, data blocks may be unavailable from the entire cluster.
-This means that even using `garage repair blocks`, some nodes may be unable
-to fetch data blocks for which they hold a reference.
-
-These errors are stored on each node in a list of "block resync errors", i.e.
-blocks for which the last resync operation failed.
-This list can be inspected using `garage block list-errors`.
-These errors usually fall into one of the following categories:
-
-1. a block is still referenced but the object was deleted, this is a case
-   of metadata reference inconsistency (see below for the fix)
-2. a block is referenced by a non-deleted object, but could not be fetched due
-   to a transient error such as a network failure
-3. a block is referenced by a non-deleted object, but could not be fetched due
-   to a permanent error such as there not being any valid copy of the block on the
-   entire cluster
-
-To help make the difference between cases 1 and cases 2 and 3, you may use the
-`garage block info` command to see which objects hold a reference to each block.
-
-In the second case (transient errors), Garage will try to fetch the block again
-after a certain time, so the error should disappear naturally. You can also
-request Garage to try to fetch the block immediately using `garage block retry-now`
-if you have fixed the transient issue.
-
-If you are confident that you are in the third scenario and that your data block
-is definitely lost, then there is no other choice than to declare your S3 objects
-as unrecoverable, and to delete them properly from the data store. This can be done
-using the `garage block purge` command.
-
-## Rebalancing data directories
-
-In [multi-HDD setups](@/documentation/operations/multi-hdd.md), to ensure that
-data blocks are well balanced between storage locations, you may run a
-rebalance operation using `garage repair rebalance`. This is useful when
-adding storage locations or when capacities of the storage locations have been
-changed.  Once this is finished, Garage will know for each block of a single
-possible location where it can be, which can increase access speed.  This
-operation will also move out all data from locations marked as read-only.
-
-
-# Metadata operations
-
-## Metadata snapshotting
-
-It is good practice to setup automatic snapshotting of your metadata database
-file, to recover from situations where it becomes corrupted on disk. This can
-be done at the filesystem level if you are using ZFS or BTRFS.
-
-Since Garage v0.9.4, Garage is able to take snapshots of the metadata database
-itself. This basically amounts to copying the database file, except that it can
-be run live while Garage is running without the risk of corruption or
-inconsistencies.  This can be setup to run automatically on a schedule using
-[`metadata_auto_snapshot_interval`](@/documentation/reference-manual/configuration.md#metadata_auto_snapshot_interval).
-A snapshot can also be triggered manually using the `garage meta snapshot`
-command. Note that taking a snapshot using this method is very intensive as it
-requires making a full copy of the database file, so you might prefer using
-filesystem-level snapshots if possible. To recover a corrupted node from such a
-snapshot, read the instructions
-[here](@/documentation/operations/recovering.md#corrupted_meta).
-
-## Metadata table resync
-
-Garage automatically resyncs all entries stored in the metadata tables every hour,
-to ensure that all nodes have the most up-to-date version of all the information
-they should be holding.
-The resync procedure is based on a Merkle tree that allows to efficiently find
-differences between nodes.
-
-In some special cases, e.g. before an upgrade, you might want to run a table
-resync manually. This can be done using `garage repair tables`.
-
-## Metadata table reference fixes
-
-In some very rare cases where nodes are unavailable, some references between objects
-are broken. For instance, if an object is deleted, the underlying versions or data
-blocks may still be held by Garage. If you suspect that such corruption has occurred
-in your cluster, you can run one of the following repair procedures:
-
-- `garage repair versions`: checks that all versions belong to a non-deleted object, and purges any orphan version
-
-- `garage repair block-refs`: checks that all block references belong to a non-deleted object version, and purges any orphan block reference (this will then allow the blocks to be garbage-collected)
-
-- `garage repair block-rc`: checks that the reference counters for blocks are in sync with the actual number of non-deleted entries in the block reference table

-The cluster layout in Garage is a table that assigns to each node a role in
-the cluster. The role of a node in Garage can either be a storage node with
-a certain capacity, or a gateway node that does not store data and is only
-used as an API entry point for faster cluster access.
-An introduction to building cluster layouts can be found in the [production deployment](@/documentation/cookbook/real-world.md) page.
-
-In Garage, all of the data that can be stored in a given cluster is divided
-into slices which we call *partitions*. Each partition is stored by
-one or several nodes in the cluster
-(see [`replication_factor`](@/documentation/reference-manual/configuration.md#replication_factor)).
-The layout determines the correspondence between these partitions,
-which exist on a logical level, and actual storage nodes.
-
-## How cluster layouts work in Garage
-
-A cluster layout is composed of the following components:
-
-- a table of roles assigned to nodes, defined by the user
-- an optimal assignation of partitions to nodes, computed by an algorithm that is ran once when calling `garage layout apply` or the ApplyClusterLayout API endpoint
-- a version number
-
-Garage nodes will always use the cluster layout with the highest version number.
-
-Garage nodes also maintain and synchronize between them a set of proposed role
-changes that haven't yet been applied. These changes will be applied (or
-canceled) in the next version of the layout.
-
-All operations on the layout can be realized using the `garage` CLI or using the
-[administration API endpoint](@/documentation/reference-manual/admin-api.md).
-We give here a description of CLI commands, the admin API semantics are very similar.
-
-The following commands insert modifications to the set of proposed role changes
-for the next layout version (but they do not create the new layout immediately):
-
-```bash
-garage layout assign [...]
-garage layout remove [...]
-```
-
-The following command can be used to inspect the layout that is currently set in the cluster
-and the changes proposed for the next layout version, if any:
-
-```bash
-garage layout show
-```
-
-The following commands create a new layout with the specified version number,
-that either takes into account the proposed changes or cancels them:
-
-```bash
-garage layout apply --version <new_version_number>
-garage layout revert --version <new_version_number>
-```
-
-The version number of the new layout to create must be 1 + the version number
-of the previous layout that existed in the cluster.  The `apply` and `revert`
-commands will fail otherwise.
-
-## Warnings about Garage cluster layout management
-
-**⚠️ Never make several calls to `garage layout apply` or `garage layout
-revert` with the same value of the `--version` flag. Doing so can lead to the
-creation of several different layouts with the same version number, in which
-case your Garage cluster will become inconsistent until fixed.** If a call to
-`garage layout apply` or `garage layout revert` has failed and `garage layout
-show` indicates that a new layout with the given version number has not been
-set in the cluster, then it is fine to call the command again with the same
-version number.
-
-If you are using the `garage` CLI by typing individual commands in your
-shell, you shouldn't have much issues as long as you run commands one after
-the other and take care of checking the output of `garage layout show`
-before applying any changes.
-
-If you are using the `garage` CLI or the admin API to script layout changes,
-follow the following recommendations:
-
-- If using the CLI, make all of your `garage` CLI calls to the same RPC host.
-  If using the admin API, make all of your API calls to the same Garage node. Do
-  not connect to individual nodes to send them each a piece of the layout changes
-  you are making, as the changes propagate asynchronously between nodes and might
-  not all be taken into account at the time when the new layout is applied.
-
-- **Only call `garage layout apply`/ApplyClusterLayout once**, and call it
-  **strictly after** all of the `layout assign` and `layout remove`
-  commands/UpdateClusterLayout API calls have returned.
-
-
-## Understanding unexpected layout calculations
-
-When adding, removing or modifying nodes in a cluster layout, sometimes
-unexpected assignations of partitions to node can occur. These assignations
-are in fact normal and logical, given the objectives of the algorithm.  Indeed,
-**the layout algorithm prioritizes moving less data between nodes over
-achieving equal distribution of load. It also tries to use all links between
-pairs of nodes in equal proportions when moving data.**  This section presents
-two examples and illustrates how one can control Garage's behavior to obtain
-the desired results.
-
-### Example 1
-
-In this example, a cluster is originally composed of 3 nodes in 3 different
-zones (data centers).  The three nodes are of equal capacity, therefore they
-are all fully exploited and all store a copy of all of the data in the cluster.
-
-Then, a fourth node of the same size is added in the datacenter `dc1`.
-As illustrated by the following, **Garage will by default not store any data on the new node**:

-```
-
-While unexpected, this is logical because of the following facts:
-
-- storing some data on the new node does not help increase the total quantity
-  of data that can be stored on the cluster, as the two other zones (`dc2` and
-  `dc3`) still need to store a full copy of everything, and their capacity is
-  still the same;
-
-- there is therefore no need to move any data on the new node as this would be pointless;
-
-- moving data to the new node has a cost which the algorithm decides to not pay if not necessary.
-
-This distribution of data can however not be what the administrator wanted: if
-they added a new node to `dc1`, it might be because the existing node is too
-slow, and they wish to divide its load by half. In that case, what they need to
-do to force Garage to distribute the data between the two nodes is to attribute
-only half of the capacity to each node in `dc1` (in our example, 500M instead of 1G).
-In that case, Garage would determine that to be able to store 1G in total, it
-would need to store 500M on the old node and 500M on the added one.
-
-
-### Example 2
-
-The following example is a slightly different scenario, where `dc1` had two
-nodes that were used at 50%, and `dc2` and `dc3` each have one node that is
-100% used. All node capacities are the same.
-
-Then, a node from `dc1` is moved into `dc3`. One could expect that the roles of
-`dc1` and `dc3` would simply be swapped: the remaining node in `dc1` would be
-used at 100%, and the two nodes now in `dc3` would be used at 50%. Instead,
-this happens:

-- node1 will now be the only node remaining in `dc1`, thus it has to store all
-  of the data in the cluster. Since it was storing only half of it before, it has
-  to retrieve the other half from other nodes in the cluster.
-
-- The data which it does not have is entirely stored by the other node that was
-  in `dc1` and that is now in `dc3` (node4). There is also a copy of it on node2
-  and node3 since both these nodes have a copy of everything.
-
-- node3 and node4 are the two nodes that will now be in a datacenter that is
- under-utilized (`dc3`), this means that those are the two candidates from which
- data can be removed to be moved to node1.
-
-- Garage will move data in equal proportions from all possible sources, in this
-  case it means that it will tranfer 25% of the entire data set from node3 to
-  node1 and another 25% from node4 to node1.
-
-This explains why node3 ends with 75% utilization (100% from before minus 25%
-that is moved to node1), and node4 ends with 25% (50% from before minus 25%
-that is moved to node1).
-
-This illustrates the second principle of the layout computation: **if there is
-a choice in moving data out of some nodes, then all links between pairs of
-nodes are used in equal proportions** (this is approximately true, there is
-randomness in the algorithm to achieve this so there might be some small
-fluctuations, as we see above).

-
-Since v0.9, Garage natively supports nodes that have several storage drives
-for storing data blocks (not for metadata storage).
-
-## Initial setup
-
-To set up a new Garage storage node with multiple HDDs,
-format and mount all your drives in different directories,
-and use a Garage configuration as follows:
-
-```toml
-data_dir = [
-    { path = "/path/to/hdd1", capacity = "2T" },
-    { path = "/path/to/hdd2", capacity = "4T" },
-]
-```
-
-Garage will automatically balance all blocks stored by the node
-among the different specified directories, proportionnally to the
-specified capacities.
-
-## Updating the list of storage locations
-
-If you add new storage locations to your `data_dir`,
-Garage will not rebalance existing data between storage locations.
-Newly written blocks will be balanced proportionnally to the specified capacities,
-and existing data may be moved between drives to improve balancing,
-but only opportunistically when a data block is re-written (e.g. an object
-is re-uploaded, or an object with a duplicate block is uploaded).
-
-To understand precisely what is happening, we need to dive in to how Garage
-splits data among the different storage locations.
-
-First of all, Garage divides the set of all possible block hashes
-in a fixed number of slices (currently 1024), and assigns
-to each slice a primary storage location among the specified data directories.
-The number of slices having their primary location in each data directory
-is proportionnal to the capacity specified in the config file.
-
-When Garage receives a block to write, it will always write it in the primary
-directory of the slice that contains its hash.
-
-Now, to be able to not lose existing data blocks when storage locations
-are added, Garage also keeps a list of secondary data directories
-for all of the hash slices. Secondary data directories for a slice indicates
-storage locations that once were primary directories for that slice, i.e. where
-Garage knows that data blocks of that slice might be stored.
-When Garage is requested to read a certain data block,
-it will first look in the primary storage directory of its slice,
-and if it doesn't find it there it goes through all of the secondary storage
-locations until it finds it. This allows Garage to continue operating
-normally when storage locations are added, without having to shuffle
-files between drives to place them in the correct location.
-
-This relatively simple strategy works well but does not ensure that data
-is correctly balanced among drives according to their capacity.
-To rebalance data, two strategies can be used:
-
-- Lazy rebalancing: when a block is re-written (e.g. the object is re-uploaded),
-  Garage checks whether the existing copy is in the primary directory of the slice
-  or in a secondary directory. If the current copy is in a secondary directory,
-  Garage re-writes a copy in the primary directory and deletes the one from the
-  secondary directory. This might never end up rebalancing everything if there
-  are data blocks that are only read and never written.
-
-- Active rebalancing: an operator of a Garage node can explicitly launch a repair
-  procedure that rebalances the data directories, moving all blocks to their
-  primary location. Once done, all secondary locations for all hash slices are
-  removed so that they won't be checked anymore when looking for a data block.
-
-## Read-only storage locations
-
-If you would like to move all data blocks from an existing data directory to one
-or several new data directories, mark the old directory as read-only:
-
-```toml
-data_dir = [
-    { path = "/path/to/old_data", read_only = true },
-    { path = "/path/to/new_hdd1", capacity = "2T" },
-    { path = "/path/to/new_hdd2", capacity = "4T" },
-]
-```
-
-Garage will be able to read requested blocks from the read-only directory.
-Garage will also move data out of the read-only directory either progressively
-(lazy rebalancing) or if requested explicitly (active rebalancing).
-
-Once an active rebalancing has finished, your read-only directory should be empty:
-it might still contain subdirectories, but no data files. You can check that
-it contains no files using:
-
-```bash
-find -type f /path/to/old_data      # should not print anything
-```
-
-at which point it can be removed from the `data_dir` list in your config file.

-
-Garage is a stateful clustered application, where all nodes are communicating together and share data structures.
-It makes upgrade more difficult than stateless applications so you must be more careful when upgrading.
-On a new version release, there is 2 possibilities:
-  - protocols and data structures remained the same ➡️ this is a **minor upgrade**
-  - protocols or data structures changed  ➡️  this is a **major upgrade**
-
-You can quickly know what type of update you will have to operate by looking at the version identifier:
-when we require our users to do a major upgrade, we will always bump the first nonzero component of the version identifier
-(e.g. from v0.7.2 to v0.8.0).
-Conversely, for versions that only require a minor upgrade, the first nonzero component will always stay the same (e.g. from v0.8.0 to v0.8.1).
-
-Major upgrades are designed to be run only between contiguous versions.
-Example: migrations from v0.7.1 to v0.8.0 and from v0.7.0 to v0.8.2 are supported but migrations from v0.6.0 to v0.8.0 are not supported.
-
-The `garage_build_info`
-[Prometheus metric](@/documentation/reference-manual/monitoring.md) provides
-an overview for which Garage versions are currently in use within a cluster.
-
-## Minor upgrades
-
-Minor upgrades do not imply cluster downtime.
-Before upgrading, you should still read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and ideally test your deployment on a staging cluster before.
-
-When you are ready, start by checking the health of your cluster.
-You can force some checks with `garage repair`, we recommend at least running `garage repair --all-nodes --yes tables` which is very quick to run (less than a minute).
-You will see that the command correctly terminated in the logs of your daemon, or using `garage worker list` (the repair workers should be in the `Done` state).
-
-Finally, you can simply upgrade nodes one by one.
-For each node: stop it, install the new binary, edit the configuration if needed, restart it.
-
-## Major upgrades
-
-Major upgrades can be done with minimal downtime with a bit of preparation, but the simplest way is usually to put the cluster offline for the duration of the migration.
-Before upgrading, you must read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and you must test your deployment on a staging cluster before.
-
-We write guides for each major upgrade, they are stored under the "Working Documents" section of this documentation.
-
-### Major upgrades with full downtime
-
-From a high level perspective, a major upgrade looks like this:
-
-  1. Disable API access (for instance in your reverse proxy, or by commenting the corresponding section in your Garage configuration file and restarting Garage)
-  2. Check that your cluster is idle
-  3. Make sure the health of your cluster is good (see `garage repair`)
-  4. Stop the whole cluster
-  5. Back up the metadata folder of all your nodes, so that you will be able to restore it if the upgrade fails (data blocks being immutable, they should not be impacted)
-  6. Install the new binary, update the configuration
-  7. Start the whole cluster
-  8. If needed, run the corresponding migration from `garage migrate`
-  9. Make sure the health of your cluster is good
-  10. Enable API access (reverse step 1)
-  11. Monitor your cluster while load comes back, check that all your applications are happy with this new version
-
-### Major upgarades with minimal downtime
-
-There is only one operation that has to be coordinated cluster-wide: the switch of one version of the internal RPC protocol to the next.
-This means that an upgrade with very limited downtime can simply be performed from one major version to the next by restarting all nodes
-simultaneously in the new version.
-The downtime will simply be the time required for all nodes to stop and start again, which should be less than a minute.
-If all nodes fail to stop and restart simultaneously, some nodes might be temporarily shut out from the cluster as nodes using different RPC protocol
-versions are prevented to talk to one another.
-
-The entire procedure would look something like this:
-
-1. Make sure the health of your cluster is good (see `garage repair`)
-
-2. Take each node offline individually to back up its metadata folder, bring them back online once the backup is done.
-  You can do all of the nodes in a single zone at once as that won't impact global cluster availability.
-  Do not try to make a backup of the metadata folder of a running node.
-
-  **Since Garage v0.9.4,** you can use the `garage meta snapshot --all` command
-  to take a simultaneous snapshot of the metadata database files of all your
-  nodes.  This avoids the tedious process of having to take them down one by
-  one before upgrading. Be careful that if automatic snapshotting is enabled,
-  Garage only keeps the last two snapshots and deletes older ones, so you might
-  want to disable automatic snapshotting in your upgraded configuration file
-  until you have confirmed that the upgrade ran successfully.  In addition to
-  snapshotting the metadata databases of your nodes, you should back-up at
-  least the `cluster_layout` file of one of your Garage instances (this file
-  should be the same on all nodes and you can copy it safely while Garage is
-  running).
-
-3. Prepare your binaries and configuration files for the new Garage version
-
-4. Restart all nodes simultaneously in the new version
-
-5. If any specific migration procedure is required, it is usually in one of the two cases:
-
-  - It can be run on online nodes after the new version has started, during regular cluster operation.
-  - it has to be run offline, in which case you will have to again take all nodes offline one after the other to run the repair
-
-   For this last step, please refer to the specific documentation pertaining to the version upgrade you are doing.

+Before reading the following, you need a working `mc` command on your path.
 
+Note that on certain Linux distributions such as Arch Linux, the Minio client binary
+is called `mcli` instead of `mc` (to avoid name clashes with the Midnight Commander).
 
-### Install and configure `awscli`
+### Configure `mc`

+You need your access key and secret key created above.
+We will assume you are invoking `mc` on the same machine as the Garage server,
+your S3 API endpoint is therefore `http://127.0.0.1:3900`.
+For this whole configuration, you must set an alias name: we chose `my-garage`, that you will used for all commands.
+
+Adapt the following command accordingly and run it:
 
 ```bash
-python -m pip install --user awscli
+mc alias set \
+  my-garage \
+  http://127.0.0.1:3900 \
+  <access key> \
+  <secret key> \
+  --api S3v4
 ```
 
-Now that `awscli` is installed, you must configure it to talk to your Garage instance,
+You must also add an environment variable to your configuration to

+inform MinIO of our region (`garage` by default, corresponding to the `s3_region` parameter
-named `~/.awsrc` with this content:
+in the configuration file).
+The best way is to add the following snippet to your `$HOME/.bash_profile`
+or `$HOME/.bashrc` file:
 
 ```bash
-export AWS_ACCESS_KEY_ID=xxxx      # put your Key ID here
+export MC_REGION=garage
-export AWS_SECRET_ACCESS_KEY=xxxx  # put your Secret key here
-export AWS_DEFAULT_REGION='garage'
-export AWS_ENDPOINT_URL='http://localhost:3900'
-
-aws --version
 ```
 
-Note you need to have at least `awscli` `>=1.29.0` or `>=2.13.0`, otherwise you
+### Use `mc`
-need to specify `--endpoint-url` explicitly on each `awscli` invocation.
 
-Now, each time you want to use `awscli` on this target, run:
+You can not list buckets from `mc` currently.
+
+But the following commands and many more should work:

+mc cp image.png my-garage/nextcloud-bucket
+mc cp my-garage/nextcloud-bucket/image.png .
+mc ls my-garage/nextcloud-bucket
+mc mirror localdir/ my-garage/another-bucket
 ```
 
-*You can create multiple files with different names if you 
-have multiple Garage clusters or different keys.
-Switching from one cluster to another is as simple as
-sourcing the right file.*
-
-### Example usage of `awscli`
-
-```bash
-# list buckets
-aws s3 ls
-
-# list objects of a bucket
-aws s3 ls s3://nextcloud-bucket
-
-# copy from your filesystem to garage
-aws s3 cp /proc/cpuinfo s3://nextcloud-bucket/cpuinfo.txt
-
-# copy from garage to your filesystem
-aws s3 cp s3://nextcloud-bucket/cpuinfo.txt /tmp/cpuinfo.txt
-```

-
-### On-demand TLS `GET /check`
-
-To prevent abuse for on-demand TLS, Caddy developers have specified an endpoint that can be queried by the reverse proxy
-to know if a given domain is allowed to get a certificate. Garage implements these endpoints to tell if a given domain is handled by Garage or is garbage.
-
-Garage responds with the following logic:
- - If the domain matches the pattern `<bucket-name>.<s3_api.root_domain>`, returns 200 OK
- - If the domain matches the pattern `<bucket-name>.<s3_web.root_domain>` and website is configured for `<bucket>`, returns 200 OK
- - If the domain matches the pattern `<bucket-name>` and website is configured for `<bucket>`, returns 200 OK
- - Otherwise, returns 404 Not Found, 400 Bad Request or 5xx requests.
-
-*Note 1: because in the path-style URL mode, there is only one domain that is not known by Garage, hence it is not supported by this API endpoint.
-You must manually declare the domain in your reverse-proxy. Idem for K2V.*
-
-*Note 2: buckets in a user's namespace are not supported yet by this endpoint. This is a limitation of this endpoint currently.*
-
-**Example:** Suppose a Garage instance is configured with `s3_api.root_domain = .s3.garage.localhost` and `s3_web.root_domain = .web.garage.localhost`.
-
-With a private `media` bucket (name in the global namespace, website is disabled), the endpoint will feature the following behavior:
-
-```
-$ curl -so /dev/null -w "%{http_code}" http://localhost:3903/check?domain=media.s3.garage.localhost
-200
-$ curl -so /dev/null -w "%{http_code}" http://localhost:3903/check?domain=media
-400
-$ curl -so /dev/null -w "%{http_code}" http://localhost:3903/check?domain=media.web.garage.localhost
-400
-```
-
-With a public `example.com` bucket (name in the global namespace, website is activated), the endpoint will feature the following behavior:
-
-```
-$ curl -so /dev/null -w "%{http_code}" http://localhost:3903/check?domain=example.com.s3.garage.localhost
-200
-$ curl -so /dev/null -w "%{http_code}" http://localhost:3903/check?domain=example.com

-### Environment variables {#env_variables}
-
-The following configuration parameter must be specified as an environment
-variable, it does not exist in the configuration file:
-
-- `GARAGE_LOG_TO_SYSLOG` (since v0.9.4): set this to `1` or `true` to make the
-  Garage daemon send its logs to `syslog` (using the libc `syslog` function)
-  instead of printing to stderr.
-
-The following environment variables can be used to override the corresponding
-values in the configuration file:
-
-- [`GARAGE_ALLOW_WORLD_READABLE_SECRETS`](#allow_world_readable_secrets)
-- [`GARAGE_RPC_SECRET` and `GARAGE_RPC_SECRET_FILE`](#rpc_secret)
-- [`GARAGE_ADMIN_TOKEN` and `GARAGE_ADMIN_TOKEN_FILE`](#admin_token)
-- [`GARAGE_METRICS_TOKEN` and `GARAGE_METRICS_TOKEN`](#admin_metrics_token)
-
-
-### Top-level configuration options
-
-#### `replication_factor` {#replication_factor}
-
-The replication factor can be any positive integer smaller or equal the node count in your cluster.
-The chosen replication factor has a big impact on the cluster's failure tolerancy and performance characteristics.
-
-- `1`: data stored on Garage is stored on a single node. There is no
-  redundancy, and data will be unavailable as soon as one node fails or its
-  network is disconnected.  Do not use this for anything else than test
-  deployments.
-
-- `2`: data stored on Garage will be stored on two different nodes, if possible
-  in different zones. Garage tolerates one node failure, or several nodes
-  failing but all in a single zone (in a deployment with at least two zones),
-  before losing data. Data remains available in read-only mode when one node is
-  down, but write operations will fail.
-
-- `3`: data stored on Garage will be stored on three different nodes, if
-  possible each in a different zones.  Garage tolerates two node failure, or
-  several node failures but in no more than two zones (in a deployment with at
-  least three zones), before losing data. As long as only a single node fails,
-  or node failures are only in a single zone, reading and writing data to
-  Garage can continue normally.
-
-- `5`, `7`, ...: When setting the replication factor above 3, it is most useful to
-  choose an uneven value, since for every two copies added, one more node can fail
-  before losing the ability to write and read to the cluster.
-
-Note that in modes `2` and `3`,
-if at least the same number of zones are available, an arbitrary number of failures in
-any given zone is tolerated as copies of data will be spread over several zones.
-
-**Make sure `replication_factor` is the same in the configuration files of all nodes.
-Never run a Garage cluster where that is not the case.**
-
-It is technically possible to change the replication factor although it's a
-dangerous operation that is not officially supported.  This requires you to
-delete the existing cluster layout and create a new layout from scratch,
-meaning that a full rebalancing of your cluster's data will be needed.  To do
-it, shut down your cluster entirely, delete the `custer_layout` files in the
-meta directories of all your nodes, update all your configuration files with
-the new `replication_factor` parameter, restart your cluster, and then create a
-new layout with all the nodes you want to keep.  Rebalancing data will take
-some time, and data might temporarily appear unavailable to your users.
-It is recommended to shut down public access to the cluster while rebalancing
-is in progress.  In theory, no data should be lost as rebalancing is a
-routine operation for Garage, although we cannot guarantee you that everything
- will go right in such an extreme scenario.
-
-#### `consistency_mode` {#consistency_mode}
-
-The consistency mode setting determines the read and write behaviour of your cluster.
-
-  - `consistent`: The default setting. This is what the paragraph above describes.
-    The read and write quorum will be determined so that read-after-write consistency
-    is guaranteed.
-  - `degraded`: Lowers the read
-    quorum to `1`, to allow you to read data from your cluster when several
-    nodes (or nodes in several zones) are unavailable.  In this mode, Garage
-    does not provide read-after-write consistency anymore.
-    The write quorum stays the same as in the `consistent` mode, ensuring that
-    data successfully written to Garage is stored on multiple nodes (depending
-    the replication factor).
-  - `dangerous`: This mode lowers both the read
-    and write quorums to `1`, to allow you to both read and write to your
-    cluster when several nodes (or nodes in several zones) are unavailable.  It
-    is the least consistent mode of operation proposed by Garage, and also one
-    that should probably never be used.
-
-Changing the `consistency_mode` between modes while leaving the `replication_factor` untouched
-(e.g. setting your node's `consistency_mode` to `degraded` when it was previously unset, or from
-`dangerous` to `consistent`), can be done easily by just changing the `consistency_mode`
-parameter in your config files and restarting all your Garage nodes.
-
-The consistency mode can be used together with various replication factors, to achieve
-a wide range of read and write characteristics. Some examples:
-
-  - Replication factor `2`, consistency mode `degraded`: While this mode
-    technically exists, its properties are the same as with consistency mode `consistent`,
-    since the read quorum with replication factor `2`, consistency mode `consistent` is already 1.
-
-  - Replication factor `2`, consistency mode `dangerous`: written objects are written to
-    the second replica asynchronously. This means that Garage will return `200
-    OK` to a PutObject request before the second copy is fully written (or even
-    before it even starts being written).  This means that data can more easily
-    be lost if the node crashes before a second copy can be completed.  This
-    also means that written objects might not be visible immediately in read
-    operations.  In other words, this configuration severely breaks the consistency and
-    durability guarantees of standard Garage cluster operation.  Benefits of
-    this configuration: you can still write to your cluster when one node is
-    unavailable.
-
-The quorums associated with each replication mode are described below:
-
-| `consistency_mode` | `replication_factor` | Write quorum | Read quorum | Read-after-write consistency? |
-| ------------------ | -------------------- | ------------ | ----------- | ----------------------------- |
-| `consistent`       | 1                    | 1            | 1           | yes                           |
-| `consistent`       | 2                    | 2            | 1           | yes                           |
-| `dangerous`        | 2                    | 1            | 1           | NO                            |
-| `consistent`       | 3                    | 2            | 2           | yes                           |
-| `degraded`         | 3                    | 2            | 1           | NO                            |
-| `dangerous`        | 3                    | 1            | 1           | NO                            |
-
-#### `metadata_dir` {#metadata_dir}

 the network configuration and the peer list, the list of buckets and keys as well
@@ -275,172 +58,18 @@ as the index of all objects, object version and object blocks.

-#### `data_dir` {#data_dir}
+### `data_dir`
 
 The directory in which Garage will store the data blocks of objects.
 This folder can be placed on an HDD. The space available for `data_dir`
 should be counted to determine a node's capacity
 when [adding it to the cluster layout](@/documentation/cookbook/real-world.md).
 
-Since `v0.9.0`, Garage supports multiple data directories with the following syntax:
+### `block_size`
-
-```toml
-data_dir = [
-    { path = "/path/to/old_data", read_only = true },
-    { path = "/path/to/new_hdd1", capacity = "2T" },
-    { path = "/path/to/new_hdd2", capacity = "4T" },
-]
-```
-
-See [the dedicated documentation page](@/documentation/operations/multi-hdd.md)
-on how to operate Garage in such a setup.
-
-#### `db_engine` (since `v0.8.0`) {#db_engine}
-
-Since `v0.8.0`, Garage can use alternative storage backends as follows:
-
-| DB engine | `db_engine` value | Database path |
-| --------- | ----------------- | ------------- |
-| [LMDB](https://www.symas.com/lmdb) (since `v0.8.0`, default since `v0.9.0`) | `"lmdb"` | `<metadata_dir>/db.lmdb/` |
-| [Sqlite](https://sqlite.org) (since `v0.8.0`) | `"sqlite"` | `<metadata_dir>/db.sqlite` |
-| [Sled](https://sled.rs) (old default, removed since `v1.0`) | `"sled"` | `<metadata_dir>/db/` |
-
-Sled was supported until Garage v0.9.x, and was removed in Garage v1.0.
-You can still use an older binary of Garage (e.g. v0.9.4) to migrate
-old Sled metadata databases to another engine.
-
-Performance characteristics of the different DB engines are as follows:
-
-- LMDB: the recommended database engine for high-performance distributed clusters.
-LMDB works very well, but is known to have the following limitations:
-
-  - The data format of LMDB is not portable between architectures, so for
-    instance the Garage database of an x86-64 node cannot be moved to an ARM64
-    node.
-
-  - While LMDB can technically be used on 32-bit systems, this will limit your
-    node to very small database sizes due to how LMDB works; it is therefore
-    not recommended.
-
-  - Several users have reported corrupted LMDB database files after an unclean
-    shutdown (e.g. a power outage). This situation can generally be recovered
-    from if your cluster is geo-replicated (by rebuilding your metadata db from
-    other nodes), or if you have saved regular snapshots at the filesystem
-    level.
-
-  - Keys in LMDB are limited to 511 bytes. This limit translates to limits on
-    object keys in S3 and sort keys in K2V that are limted to 479 bytes.
-
-- Sqlite: Garage supports Sqlite as an alternative storage backend for
-  metadata, which does not have the issues listed above for LMDB.
-  On versions 0.8.x and earlier, Sqlite should be avoided due to abysmal
-  performance, which was fixed with the addition of `metadata_fsync`.
-  Sqlite is still probably slower than LMDB due to the way we use it,
-  so it is not the best choice for high-performance storage clusters,
-  but it should work fine in many cases.
-
-It is possible to convert Garage's metadata directory from one format to another
-using the `garage convert-db` command, which should be used as follows:
-
-```
-garage convert-db -a <input db engine> -i <input db path> \
-                  -b <output db engine> -o <output db path>
-```
-
-Make sure to specify the full database path as presented in the table above
-(third colummn), and not just the path to the metadata directory.
-
-#### `metadata_fsync` {#metadata_fsync}
-
-Whether to enable synchronous mode for the database engine or not.
-This is disabled (`false`) by default.
-
-This reduces the risk of metadata corruption in case of power failures,
-at the cost of a significant drop in write performance,
-as Garage will have to pause to sync data to disk much more often
-(several times for API calls such as PutObject).
-
-Using this option reduces the risk of simultaneous metadata corruption on several
-cluster nodes, which could lead to data loss.
-
-If multi-site replication is used, this option is most likely not necessary, as
-it is extremely unlikely that two nodes in different locations will have a
-power failure at the exact same time.
-
-(Metadata corruption on a single node is not an issue, the corrupted data file
-can always be deleted and reconstructed from the other nodes in the cluster.)
-
-Here is how this option impacts the different database engines:
-
-| Database | `metadata_fsync = false` (default) | `metadata_fsync = true`       |
-|----------|------------------------------------|-------------------------------|
-| Sqlite   | `PRAGMA synchronous = OFF`         | `PRAGMA synchronous = NORMAL` |
-| LMDB     | `MDB_NOMETASYNC` + `MDB_NOSYNC`    | `MDB_NOMETASYNC`              |
-
-Note that the Sqlite database is always ran in `WAL` mode (`PRAGMA journal_mode = WAL`).
-
-#### `data_fsync` {#data_fsync}
-
-Whether to `fsync` data blocks and their containing directory after they are
-saved to disk.
-This is disabled (`false`) by default.
-
-This might reduce the risk that a data block is lost in rare
-situations such as simultaneous node losing power,
-at the cost of a moderate drop in write performance.
-
-Similarly to `metatada_fsync`, this is likely not necessary
-if geographical replication is used.
-
-#### `metadata_auto_snapshot_interval` (since Garage v0.9.4) {#metadata_auto_snapshot_interval}
-
-If this value is set, Garage will automatically take a snapshot of the metadata
-DB file at a regular interval and save it in the metadata directory.
-This parameter can take any duration string that can be parsed by

-
-### S3 API
-
-The main goal of Garage is to provide an object storage service that is compatible with the
-[S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html) from Amazon Web Services.
-We try to adhere as strictly as possible to the semantics of the API as implemented by Amazon
-and other vendors such as Minio or CEPH.
-
-Of course Garage does not implement the full span of API endpoints that AWS S3 does;
-the exact list of S3 features implemented by Garage can be found [on our S3 compatibility page](@/documentation/reference-manual/s3-compatibility.md).
-
-### Geo-distribution
-
-Garage allows you to store copies of your data in multiple geographical locations in order to maximize resilience
-to adverse events, such as network/power outages or hardware failures.
-This allows Garage to run very well even at home, using consumer-grade Internet connectivity
-(such as FTTH) and power, as long as cluster nodes can be spawned at several physical locations.
-Garage exploits knowledge of the capacity and physical location of each storage node to design
-a storage plan that best exploits the available storage capacity while satisfying the geo-distributed replication constraint.
-
-To learn more about geo-distributed Garage clusters,
-read our documentation on [setting up a real-world deployment](@/documentation/cookbook/real-world.md).
-
-### Standalone/self-contained
-
-Garage is extremely simple to deploy, and does not depend on any external service to run.
-This makes setting up and administering storage clusters, we hope, as easy as it could be.
-
-### Flexible topology
-
-A Garage cluster can very easily evolve over time, as storage nodes are added or removed.
-Garage will automatically rebalance data between nodes as needed to ensure the desired number of copies.
-Read about cluster layout management [here](@/documentation/operations/layout.md).
-
-### Several replication modes
-
-Garage supports a variety of replication modes, with configurable replica count,
-and with various levels of consistency, in order to adapt to a variety of usage scenarios.
-Read our reference page on [supported replication modes](@/documentation/reference-manual/configuration.md#replication_factor)
-to select the replication mode best suited to your use case (hint: in most cases, `replication_factor = 3` is what you want).
-
-### Compression and deduplication
-
-All data stored in Garage is deduplicated, and optionnally compressed using
-Zstd.  Objects uploaded to Garage are chunked in blocks of constant sizes (see
-[`block_size`](@/documentation/reference-manual/configuration.md#block_size)),
-and the hashes of individual blocks are used to dispatch them to storage nodes
-and to deduplicate them.
-
-### No RAFT slowing you down
-
-It might seem strange to tout the absence of something as a desirable feature,
-but this is in fact a very important point! Garage does not use RAFT or another
-consensus algorithm internally to order incoming requests: this means that all requests
-directed to a Garage cluster can be handled independently of one another instead
-of going through a central bottleneck (the leader node).
-As a consequence, requests can be handled much faster, even in cases where latency
-between cluster nodes is important (see our [benchmarks](@/documentation/design/benchmarks/index.md) for data on this).
-This is particularly usefull when nodes are far from one another and talk to one other through standard Internet connections.
-
-### Web server for static websites
-
-A storage bucket can easily be configured to be served directly by Garage as a static web site.
-Domain names for multiple websites directly map to bucket names, making it easy to build
-a platform for your users to autonomously build and host their websites over Garage.
-Surprisingly, none of the other alternative S3 implementations we surveyed (such as Minio
-or CEPH) support publishing static websites from S3 buckets, a feature that is however
-directly inherited from S3 on AWS.
-Read more on our [dedicated documentation page](@/documentation/cookbook/exposing-websites.md).
-
-### Bucket names as aliases
-
-In Garage, a bucket may have several names, known as aliases.
-Aliases can easily be added and removed on demand:
-this allows to easily rename buckets if needed
-without having to copy all of their content, something that cannot be done on AWS.
-For buckets served as static websites, having multiple aliases for a bucket can allow
-exposing the same content under different domain names.
-
-Garage also supports bucket aliases which are local to a single user:
-this allows different users to have different buckets with the same name, thus avoiding naming collisions.
-This can be helpfull for instance if you want to write an application that creates per-user buckets with always the same name.
-
-This feature is totally invisible to S3 clients and does not break compatibility with AWS.
-
-### Cluster administration API
-
-Garage provides a fully-fledged REST API to administer your cluster programatically.
-Functionality included in the admin API include: setting up and monitoring
-cluster nodes, managing access credentials, and managing storage buckets and bucket aliases.
-A full reference of the administration API is available [here](@/documentation/reference-manual/admin-api.md).
-
-### Metrics and traces
-
-Garage makes some internal metrics available in the Prometheus data format,
-which allows you to build interactive dashboards to visualize the load and internal state of your storage cluster.
-
-For developpers and performance-savvy administrators,
-Garage also supports exporting traces of what it does internally in OpenTelemetry format.
-This allows to monitor the time spent at various steps of the processing of requests,
-in order to detect potential performance bottlenecks.
-
-### Kubernetes and Nomad integrations
-
-Garage can automatically discover other nodes in the cluster thanks to integration
-with orchestrators such as Kubernetes and Nomad (when used with Consul).
-This eases the configuration of your cluster as it removes one step where nodes need
-to be manually connected to one another.
-
-### Support for changing IP addresses
-
-As long as all of your nodes don't change their IP address at the same time,
-Garage should be able to tolerate nodes with changing/dynamic IP addresses,
-as nodes will regularly exchange the IP addresses of their peers and try to
-reconnect using newer addresses when existing connections are broken.
-
-### K2V API (experimental)
-
-As part of an ongoing research project, Garage can expose an experimental key/value storage API called K2V.
-K2V is made for the storage and retrieval of many small key/value pairs that need to be processed in bulk.
-This completes the S3 API with an alternative that can be used to easily store and access metadata
-related to objects stored in an S3 bucket.
-
-In the context of our research project, [Aérogramme](https://aerogramme.deuxfleurs.fr),
-K2V is used to provide metadata and log storage for operations on encrypted e-mail storage.

-Starting with version 0.7.2, Garage introduces an optional feature, K2V,
-which is an alternative storage API designed to help efficiently store
-many small values in buckets (in opposition to S3 which is more designed
-to store large blobs).
-
-K2V is currently disabled at compile time in all builds, as the
-specification is still subject to changes. To build a Garage version with
-K2V, the Cargo feature flag `k2v` must be activated.  Special builds with
-the `k2v` feature flag enabled can be obtained from our download page under
-"Extra builds": such builds can be identified easily as their tag name ends
-with `-k2v` (example: `v0.7.2-k2v`).
-
-The specification of the K2V API can be found
-[here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/main/doc/drafts/k2v-spec.md).
-This document also includes a high-level overview of K2V's design.
-
-The K2V API uses AWSv4 signatures for authentification, same as the S3 API.
-The AWS region used for signature calculation is always the same as the one

+
+The cluster layout in Garage is a table that assigns to each node a role in
+the cluster. The role of a node in Garage can either be a storage node with
+a certain capacity, or a gateway node that does not store data and is only
+used as an API entry point for faster cluster access.
+An introduction to building cluster layouts can be found in the [production deployment](@/documentation/cookbook/real-world.md) page.
+
+## How cluster layouts work in Garage
+
+In Garage, a cluster layout is composed of the following components:
+
+- a table of roles assigned to nodes
+- a version number
+
+Garage nodes will always use the cluster layout with the highest version number.
+
+Garage nodes also maintain and synchronize between them a set of proposed role
+changes that haven't yet been applied. These changes will be applied (or
+canceled) in the next version of the layout
+
+The following commands insert modifications to the set of proposed role changes
+for the next layout version (but they do not create the new layout immediately):
+
+```bash
+garage layout assign [...]
+garage layout remove [...]
+```
+
+The following command can be used to inspect the layout that is currently set in the cluster
+and the changes proposed for the next layout version, if any:
+
+```bash
+garage layout show
+```
+
+The following commands create a new layout with the specified version number,
+that either takes into account the proposed changes or cancels them:
+
+```bash
+garage layout apply --version <new_version_number>
+garage layout revert --version <new_version_number>
+```
+
+The version number of the new layout to create must be 1 + the version number
+of the previous layout that existed in the cluster.  The `apply` and `revert`
+commands will fail otherwise.
+
+## Warnings about Garage cluster layout management
+
+**Warning: never make several calls to `garage layout apply` or `garage layout
+revert` with the same value of the `--version` flag. Doing so can lead to the
+creation of several different layouts with the same version number, in which
+case your Garage cluster will become inconsistent until fixed.** If a call to
+`garage layout apply` or `garage layout revert` has failed and `garage layout
+show` indicates that a new layout with the given version number has not been
+set in the cluster, then it is fine to call the command again with the same
+version number.
+
+If you are using the `garage` CLI by typing individual commands in your
+shell, you shouldn't have much issues as long as you run commands one after
+the other and take care of checking the output of `garage layout show`
+before applying any changes.
+
+If you are using the `garage` CLI to script layout changes, follow the following recommendations:
+
+- Make all of your `garage` CLI calls to the same RPC host. Do not use the
+  `garage` CLI to connect to individual nodes to send them each a piece of the
+  layout changes you are making, as the changes propagate asynchronously
+  between nodes and might not all be taken into account at the time when the
+  new layout is applied.
+
+- **Only call `garage layout apply` once**, and call it **strictly after** all
+  of the `layout assign` and `layout remove` commands have returned.

-## Simple migration procedure (takes cluster offline for a while)
-
-The migration steps are as follows:

-6. Install Garage v0.8
-7. **Before starting Garage v0.8**, run the offline migration step: `garage offline-repair --yes object_counters`.
-   This can take a while to run, depending on the number of objects stored in your cluster.
-8. Turn on Garage v0.8
-9. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`.
-   Wait for a full table sync to run.

-
-## Minimal downtime migration procedure
-
-The migration to Garage v0.8 can be done with almost no downtime,
-by restarting all nodes at once in the new version. The only limitation with this
-method is that bucket sizes and item counts will not be estimated correctly
-until all nodes have had a chance to run their offline migration procedure.
-
-The migration steps are as follows:
-
-1. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`,
-   check the logs and check that all data seems to be synced correctly between
-   nodes. If you have time, do additional checks (`versions`, `block_refs`, etc.)
-
-2. Turn off each node individually; back up its metadata folder (see above); turn it back on again. This will allow you to take a backup of all nodes without impacting global cluster availability. You can do all nodes of a single zone at once as this does not impact the availability of Garage.
-
-3. Prepare your binaries and configuration files for Garage v0.8
-
-4. Shut down all v0.7 nodes simultaneously, and restart them all simultaneously in v0.8. Use your favorite deployment tool (Ansible, Kubernetes, Nomad) to achieve this as fast as possible.
-
-5. At this point, Garage will indicate invalid values for the size and number of objects in each bucket (most likely, it will indicate zero). To fix this, take each node offline individually to do the offline migration step: `garage offline-repair --yes object_counters`. Again you can do all nodes of a single zone at once.

-## Changes introduced in v1.0
-
-The following are **breaking changes** in Garage v1.0 that require your attention when migrating:
-
-- The Sled metadata db engine has been **removed**. If your cluster was still
-  using Sled, you will need to **use a Garage v0.9.x binary** to convert the
-  database using the `garage convert-db` subcommand. See
-  [here](@/documentation/reference-manual/configuration.md#db_engine) for the
-  details of the procedure.
-
-The following syntax changes have been made to the configuration file:
-
-- The `replication_mode` parameter has been split into two parameters:
-  [`replication_factor`](@/documentation/reference-manual/configuration.md#replication_factor)
-  and
-  [`consistency_mode`](@/documentation/reference-manual/configuration.md#consistency_mode).
-  The old syntax using `replication_mode` is still supported for legacy
-  reasons and can still be used.
-
-- The parameters `sled_cache_capacity` and `sled_flush_every_ms` have been removed.
-
-## Migration procedure
-
-The migration to Garage v1.0 can be done with almost no downtime,
-by restarting all nodes at once in the new version.
-
-The migration steps are as follows:
-
-1. Do a `garage repair --all-nodes --yes tables`, check the logs and check that
-   all data seems to be synced correctly between nodes. If you have time, do
-   additional `garage repair` procedures (`blocks`, `versions`, `block_refs`,
-   etc.)
-
-2. Ensure you have a snapshot of your Garage installation that you can restore
-   to in case the upgrade goes wrong:
-
-   - If you are running Garage v0.9.4 or later, use the `garage meta snapshot
-     --all` to make a backup snapshot of the metadata directories of your nodes
-     for backup purposes, and save a copy of the following files in the
-     metadata directories of your nodes: `cluster_layout`, `data_layout`,
-     `node_key`, `node_key.pub`.
-
-   - If you are running a filesystem such as ZFS or BTRFS that support
-     snapshotting, you can create a filesystem-level snapshot to be used as a
-     restoration point if needed.
-
-   - In other cases, make a backup using the old procedure: turn off each node
-     individually; back up its metadata folder (for instance, use the following
-     command if your metadata directory is `/var/lib/garage/meta`: `cd
-     /var/lib/garage ; tar -acf meta-v0.9.tar.zst meta/`); turn it back on
-     again.  This will allow you to take a backup of all nodes without
-     impacting global cluster availability.  You can do all nodes of a single
-     zone at once as this does not impact the availability of Garage.
-
-3. Prepare your updated binaries and configuration files for Garage v1.0
-
-4. Shut down all v0.9 nodes simultaneously, and restart them all simultaneously
-   in v1.0.  Use your favorite deployment tool (Ansible, Kubernetes, Nomad) to
-   achieve this as fast as possible.  Garage v1.0 should be in a working state
-   as soon as enough nodes have started.
-
-5. Monitor your cluster in the following hours to see if it works well under
-   your production load.

-## Testing Garage
-
-Currently, we have the following tests:
-
-- some unit tests spread around the codebase
-- integration tests written in Rust (`src/garage/test`) to check that Garage operations perform correctly
-- integration test for compatibility with external tools (`script/test-smoke.sh`)
-
-We have also tried `minio/mint` but it fails a lot and for now we haven't gotten a lot from it.
-
-In the future:
-
-1. We'd like to have a systematic way of testing with `minio/mint`,
-   it would add value to Garage by providing a compatibility score and reference that can be trusted.
-2. We'd also like to do testing with Jepsen in some way.
-
-## How to instrument Garagae
-
-We should try to test in least invasive ways, i.e. minimize the impact of the testing framework on Garage's source code. This means for example:
-
-- Not abstracting IO/nondeterminism in the source code
-- Not making `garage` a shared library (launch using `execve`, it's perfectly fine)
-
-Instead, we should focus on building a clean outer interface for the `garage` binary,
-for example loading configuration using environnement variables instead of the configuration file if that's helpfull for writing the tests.
-
-There are two reasons for this:
-
-- Keep the soure code clean and focused
-- Test something that is as close as possible as the true garage that will actually be running
-
-Reminder: rules of simplicity, concerning changes to Garage's source code.
-Always question what we are doing.
-Never do anything just because it looks nice or because we "think" it might be usefull at some later point but without knowing precisely why/when.
-Only do things that make perfect sense in the context of what we currently know.
-

-
-The Garage administration API is accessible through a dedicated server whose
-listen address is specified in the `[admin]` section of the configuration
-file (see [configuration file
-reference](@/documentation/reference-manual/configuration.md))
-
-**WARNING.** At this point, there is no commitment to the stability of the APIs described in this document.
-We will bump the version numbers prefixed to each API endpoint each time the syntax
-or semantics change, meaning that code that relies on these endpoints will break
-when changes are introduced.
-
-The Garage administration API was introduced in version 0.7.2, this document
-does not apply to older versions of Garage.
-
-
-## Access control
-
-The admin API uses two different tokens for access control, that are specified in the config file's `[admin]` section:
-
-- `metrics_token`: the token for accessing the Metrics endpoint (if this token
-  is not set in the config file, the Metrics endpoint can be accessed without
-  access control);
-
-- `admin_token`: the token for accessing all of the other administration
-  endpoints (if this token is not set in the config file, access to these
-  endpoints is disabled entirely).
-
-These tokens are used as simple HTTP bearer tokens. In other words, to
-authenticate access to an admin API endpoint, add the following HTTP header
-to your request:
-
-```
-Authorization: Bearer <token>
-```
-
-## Administration API endpoints
-
-### Metrics-related endpoints
-
-#### Metrics `GET /metrics`
-
-Returns internal Garage metrics in Prometheus format.
-
-#### Health `GET /health`
-
-Used for simple health checks in a cluster setting with an orchestrator.
-Returns an HTTP status 200 if the node is ready to answer user's requests,
-and an HTTP status 503 (Service Unavailable) if there are some partitions
-for which a quorum of nodes is not available.
-A simple textual message is also returned in a body with content-type `text/plain`.
-See `/v1/health` for an API that also returns JSON output.

-
-#### GetClusterHealth `GET /v1/health`
-
-Returns the cluster's current health in JSON format, with the following variables:
-
-- `status`: one of `healthy`, `degraded` or `unavailable`:
-  - healthy: Garage node is connected to all storage nodes
-  - degraded: Garage node is not connected to all storage nodes, but a quorum of write nodes is available for all partitions
-  - unavailable: a quorum of write nodes is not available for some partitions
-- `knownNodes`: the number of nodes this Garage node has had a TCP connection to since the daemon started
-- `connectedNodes`: the nubmer of nodes this Garage node currently has an open connection to
-- `storageNodes`: the number of storage nodes currently registered in the cluster layout
-- `storageNodesOk`: the number of storage nodes to which a connection is currently open
-- `partitions`: the total number of partitions of the data (currently always 256)
-- `partitionsQuorum`: the number of partitions for which a quorum of write nodes is available
-- `partitionsAllOk`: the number of partitions for which we are connected to all storage nodes responsible of storing it
-
-Contrarily to `GET /health`, this endpoint always returns a 200 OK HTTP response code.
-
-Example response body:
-
-```json
-{
-  "status": "degraded",
-  "knownNodes": 3,
-  "connectedNodes": 3,
-  "storageNodes": 4,
-  "storageNodesOk": 3,

-    "4a6ae5a1d0d33bf895f5bb4f0a418b7dc94c47c0dd2eb108d1158f3c8f60b0ff@10.0.0.12:3901"
-]
-```
-
-The format of the string for a node to connect to is: `<node ID>@<ip address>:<port>`, same as in the `garage node connect` CLI call.
-
-Example response:
-
-```json
-[
-    {
-        "success": true,
-        "error": null
-    },
-    {

-    }
-]
-```
-
-#### GetClusterLayout `GET /v1/layout`
-
-Returns the cluster's current layout in JSON, including:
-
-- Currently configured cluster layout
-- Staged changes to the cluster layout
-
-(the info returned by this endpoint is a subset of the info returned by GetClusterStatus)
-

-```
-
-#### UpdateClusterLayout `POST /v1/layout`
-
-Send modifications to the cluster layout. These modifications will
-be included in the staged role changes, visible in subsequent calls
-of `GetClusterLayout`. Once the set of staged changes is satisfactory,
-the user may call `ApplyClusterLayout` to apply the changed changes,
-or `Revert ClusterLayout` to clear all of the staged changes in
-the layout.
-
-Request body format:
-
-```json
-[
-  {
-    "id": <node_id>,
-    "capacity": <new_capacity>,
-    "zone": <new_zone>,
-    "tags": [
-      <new_tag>,
-      ...
-    ]
-  },
-  {
-    "id": <node_id_to_remove>,
-    "remove": true
-  }
-]
-```
-
-Contrary to the CLI that may update only a subset of the fields
-`capacity`, `zone` and `tags`, when calling this API all of these
-values must be specified.
-
-This returns the new cluster layout with the proposed staged changes,
-as returned by GetClusterLayout.
-
-
-#### ApplyClusterLayout `POST /v1/layout/apply`
-
-Applies to the cluster the layout changes currently registered as
-staged layout changes.
-
-Request body format:
-
-```json
-{
-  "version": 13
-}
-```
-
-Similarly to the CLI, the body must include the version of the new layout
-that will be created, which MUST be 1 + the value of the currently
-existing layout in the cluster.
-
-This returns the message describing all the calculations done to compute the new
-layout, as well as the description of the layout as returned by GetClusterLayout.
-
-#### RevertClusterLayout `POST /v1/layout/revert`
-
-Clears all of the staged layout changes.
-
-Request body format:
-
-```json
-{
-  "version": 13
-}
-```
-
-Reverting the staged changes is done by incrementing the version number
-and clearing the contents of the staged change list.
-Similarly to the CLI, the body must include the incremented
-version number, which MUST be 1 + the value of the currently
-existing layout in the cluster.
-
-This returns the new cluster layout with all changes reverted,
-as returned by GetClusterLayout.
-
-
-### Access key operations
-
-#### ListKeys `GET /v1/key`
-
-Returns all API access keys in the cluster.
-
-Example response:
-
-```json
-[
-  {
-    "id": "GK31c2f218a2e44f485b94239e",
-    "name": "test"
-  },
-  {
-    "id": "GKe10061ac9c2921f09e4c5540",
-    "name": "test2"
-  }
-]
-```
-
-#### GetKeyInfo `GET /v1/key?id=<acces key id>`
-#### GetKeyInfo `GET /v1/key?search=<pattern>`
-
-Returns information about the requested API access key.
-
-If `id` is set, the key is looked up using its exact identifier (faster).
-If `search` is set, the key is looked up using its name or prefix
-of identifier (slower, all keys are enumerated to do this).
-
-Optionnally, the query parameter `showSecretKey=true` can be set to reveal the
-associated secret access key.
-
-Example response:
-
-```json

-
-All fields (`websiteAccess` and `quotas`) are optional.
-If they are present, the corresponding modifications are applied to the bucket, otherwise nothing is changed.
-
-In `websiteAccess`: if `enabled` is `true`, `indexDocument` must be specified.
-The field `errorDocument` is optional, if no error document is set a generic
-error message is displayed when errors happen. Conversely, if `enabled` is
-`false`, neither `indexDocument` nor `errorDocument` must be specified.
-
-In `quotas`: new values of `maxSize` and `maxObjects` must both be specified, or set to `null`
-to remove the quotas. An absent value will be considered the same as a `null`. It is not possible
-to change only one of the two quotas.

-# Specification of the Garage K2V API (K2V = Key/Key/Value)
-
-- We are storing triplets of the form `(partition key, sort key, value)` -> no
-  user-defined fields, the client is responsible of writing whatever he wants
-  in the value (typically an encrypted blob). Values are binary blobs, which
-  are always represented as their base64 encoding in the JSON API. Partition
-  keys and sort keys are utf8 strings.
-
-- Triplets are stored in buckets; each bucket stores a separate set of triplets
-
-- Bucket names and access keys are the same as for accessing the S3 API
-
-- K2V triplets exist separately from S3 objects. K2V triplets don't exist for
-  the S3 API, and S3 objects don't exist for the K2V API.
-
-- Values stored for triplets have associated causality information, that enables
-  Garage to detect concurrent writes. In case of concurrent writes, Garage
-  keeps the concurrent values until a further write supersedes the concurrent
-  values. This is the same method as Riak KV implements. The method used is
-  based on DVVS (dotted version vector sets), described in the paper "Scalable
-  and Accurate Causality Tracking for Eventually Consistent Data Stores", as
-  well as [here](https://github.com/ricardobcl/Dotted-Version-Vectors)
-
-
-## Data format
-
-### Triple format
-
-Triples in K2V are constituted of three fields:
-
-- a partition key (`pk`), an utf8 string that defines in what partition the
-  triplet is stored; triplets in different partitions cannot be listed together
-  in a ReadBatch command, or deleted together in a DeleteBatch command: a
-  separate command must be included in the ReadBatch/DeleteBatch call for each
-  partition key in which the client wants to read/delete lists of items
-
-- a sort key (`sk`), an utf8 string that defines the index of the triplet inside its
-  partition; triplets are uniquely idendified by their partition key + sort key
-
-- a value (`v`), an opaque binary blob associated to the partition key + sort key;
-  they are transmitted as binary when possible but in most case in the JSON API
-  they will be represented as strings using base64 encoding; a value can also
-  be `null` to indicate a deleted triplet (a `null` value is called a tombstone)
-
-### Causality information
-
-K2V supports storing several concurrent values associated to a pk+sk, in the
-case where insertion or deletion operations are detected to be concurrent (i.e.
-there is not one that was aware of the other, they are not causally dependant
-one on the other).  In practice, it even looks more like the opposite: to
-overwrite a previously existing value, the client must give a "causality token"
-that "proves" (not in a cryptographic sense) that it had seen a previous value.
-Otherwise, the value written will not overwrite an existing value, it will just
-create a new concurrent value.
-
-The causality token is a binary/b64-encoded representation of a context,
-specified below.
-
-A set of concurrent values looks like this:
-
-```
-(node1, tdiscard1, (v1, t1), (v2, t2)) ; tdiscard1 < t1 < t2
-(node2, tdiscard2, (v3, t3)            ; tdiscard2 < t3
-```
-
-`tdiscard` for a node `i` means that all values inserted by node `i` with times
-`<= tdiscard` are obsoleted, i.e. have been read by a client that overwrote it
-afterwards.
-
-The associated context would be the following: `[(node1, t2), (node2, t3)]`,
-i.e. if a node reads this set of values and inserts a new values, we will now
-have `tdiscard1 = t2` and `tdiscard2 = t3`, to indicate that values v1, v2 and v3
-are obsoleted by the new write.
-
-**Basic insertion.** To insert a new value `v4` with context `[(node1, t2), (node2, t3)]`, in a
-simple case where there was no insertion in-between reading the value
-mentionned above and writing `v4`, and supposing that node2 receives the
-InsertItem query:
-
-- `node2` generates a timestamp `t4` such that `t4 > t3`.
-- the new state is as follows:
-
-```
-(node1, tdiscard1', ())       ; tdiscard1' = t2
-(node2, tdiscard2', (v4, t4)) ; tdiscard2' = t3
-```
-
-**A more complex insertion example.** In the general case, other intermediate values could have
-been written before `v4` with context `[(node1, t2), (node2, t3)]` is sent to the system.
-For instance, here is a possible sequence of events:
-
-1. First we have the set of values v1, v2 and v3 described above.
-   A node reads it, it obtains values v1, v2 and v3 with context `[(node1, t2), (node2, t3)]`.
-
-2. A node writes a value `v5` with context `[(node1, t1)]`, i.e. `v5` is only a
-   successor of v1 but not of v2 or v3. Suppose node1 receives the write, it
-   will generate a new timestamp `t5` larger than all of the timestamps it
-   knows of, i.e. `t5 > t2`. We will now have:
-
-```
-(node1, tdiscard1'', (v2, t2), (v5, t5)) ; tdiscard1'' = t1 < t2 < t5
-(node2, tdiscard2, (v3, t3)              ; tdiscard2 < t3
-```
-
-3. Now `v4` is written with context `[(node1, t2), (node2, t3)]`, and node2
-   processes the query. It will generate `t4 > t3` and the state will become:
-
-```
-(node1, tdiscard1', (v5, t5))       ; tdiscard1' = t2 < t5
-(node2, tdiscard2', (v4, t4))       ; tdiscard2' = t3
-```
-
-**Generic algorithm for handling insertions:** A certain node n handles the
-InsertItem and is responsible for the correctness of this procedure.
-
-1. Lock the key (or the whole table?) at this node to prevent concurrent updates of the value that would mess things up
-2. Read current set of values
-3. Generate a new timestamp that is larger than the largest timestamp for node n
-4. Add the inserted value in the list of values of node n
-5. Update the discard times to be the times set in the context, and accordingly discard overwritten values
-6. Release lock
-7. Propagate updated value to other nodes
-8. Return to user when propagation achieved the write quorum (propagation to other nodes continues asynchronously)
-
-**Encoding of contexts:**
-
-Contexts consist in a list of (node id, timestamp) pairs.
-They are encoded in binary as follows:
-
-```
-checksum: u64, [ node: u64, timestamp: u64 ]*
-```
-
-The checksum is just the XOR of all of the node IDs and timestamps.
-
-Once encoded in binary, contexts are written and transmitted in base64.
-
-
-### Indexing
-
-K2V keeps an index, a secondary data structure that is updated asynchronously,
-that keeps tracks of the number of triplets stored for each partition key.
-This allows easy listing of all of the partition keys for which triplets exist
-in a bucket, as the partition key becomes the sort key in the index.
-
-How indexing works:
-
-- Each node keeps a local count of how many items it stores for each partition,
-  in a local database tree that is updated atomically when an item is modified.
-- These local counters are asynchronously stored in the index table which is
-  a regular Garage table spread in the network. Counters are stored as LWW values,
-  so basically the final table will have the following structure:
-
-```
-- pk: bucket
-- sk: partition key for which we are counting
-- v:  lwwmap (node id -> number of items)
-```
-
-The final number of items present in the partition can be estimated by taking
-the maximum of the values (i.e. the value for the node that announces having
-the most items for that partition). In most cases the values for different node
-IDs should all be the same; more precisely, three node IDs should map to the
-same non-zero value, and all other node IDs that are present are tombstones
-that map to zeroes.  Note that we need to filter out values from nodes that are
-no longer part of the cluster layout, as when nodes are removed they won't
-necessarily have had the time to set their counters to zero.
-
-## Important details
-
-**THIS SECTION CONTAINS A FEW WARNINGS ON THE K2V API WHICH ARE IMPORTANT
-TO UNDERSTAND IN ORDER TO USE IT CORRECTLY.**
-
-- **Internal server errors on updates do not mean that the update isn't stored.**
-  K2V will return an internal server error when it cannot reach a quorum of nodes on
-  which to save an updated value. However the value may still be stored on just one
-  node, which will then propagate it to other nodes asynchronously via anti-entropy.
-
-- **Batch operations are not transactions.** When calling InsertBatch or DeleteBatch,
-  items may appear partially inserted/deleted while the operation is being processed.
-  More importantly, if InsertBatch or DeleteBatch returns an internal server error,
-  some of the items to be inserted/deleted might end up inserted/deleted on the server,
-  while others may still have their old value.
-
-- **Concurrent values are deduplicated.** When inserting a value for a key,
-  Garage might internally end up
-  storing the value several times if there are network errors. These values will end up as
-  concurrent values for a key, with the same byte string (or `null` for a deletion).
-  Garage fixes this by deduplicating concurrent values when they are returned to the
-  user on read operations. Importantly, *Garage does not differentiate between duplicate
-  concurrent values due to the user making the same call twice, or Garage having to
-  do an internal retry*. This means that all duplicate concurrent values are deduplicated
-  when an item is read: if the user inserts twice concurrently the same value, they will
-  only read it once.
-
-## API Endpoints
-
-**Remark.** Example queries and responses here are given in JSON5 format
-for clarity. However the actual K2V API uses basic JSON so all examples
-and responses need to be translated.
-
-### Operations on single items
-
-**ReadItem: `GET /<bucket>/<partition key>?sort_key=<sort key>`**
-
-
-Query parameters:
-
-| name       | default value | meaning                          |
-|------------|---------------|----------------------------------|
-| `sort_key` | **mandatory** | The sort key of the item to read |
-
-Returns the item with specified partition key and sort key. Values can be
-returned in either of two ways:
-
-1. a JSON array of base64-encoded values, or `null`'s for tombstones, with
-   header `Content-Type: application/json`
-
-2. in the case where there are no concurrent values, the single present value
-   can be returned directly as the response body (or an HTTP 204 NO CONTENT for
-   a tombstone), with header `Content-Type: application/octet-stream`
-
-The choice between return formats 1 and 2 is directed by the `Accept` HTTP header:
-
-- if the `Accept` header is not present, format 1 is always used
-
-- if `Accept` contains `application/json` but not `application/octet-stream`,
-  format 1 is always used
-
-- if `Accept` contains `application/octet-stream` but not `application/json`,
-  format 2 is used when there is a single value, and an HTTP error 409 (HTTP
-  409 CONFLICT) is returned in the case of multiple concurrent values
-  (including concurrent tombstones)
-
-- if `Accept` contains both, format 2 is used when there is a single value, and
-  format 1 is used as a fallback in case of concurrent values
-
-- if `Accept` contains none, HTTP 406 NOT ACCEPTABLE is raised
-
-Example query:
-
-```
-GET /my_bucket/mailboxes?sort_key=INBOX HTTP/1.1

-Content-Type: application/octet-stream
-```
-
-
-**PollItem: `GET /<bucket>/<partition key>?sort_key=<sort key>&causality_token=<causality token>`**
-
-This endpoint will block until a new value is written to a key.
-
-The GET parameter `causality_token` should be set to the causality
-token returned with the last read of the key, so that K2V knows
-what values are concurrent or newer than the ones that the
-client previously knew.
-
-This endpoint returns the new value in the same format as ReadItem.
-If no new value is written and the timeout elapses,
-an HTTP 304 NOT MODIFIED is returned.
-
-Query parameters:
-
-| name              | default value | meaning                                                                    |
-|-------------------|---------------|----------------------------------------------------------------------------|
-| `sort_key`        | **mandatory** | The sort key of the item to read                                           |
-| `causality_token` | **mandatory** | The causality token of the last known value or set of values               |
-| `timeout`         | 300           | The timeout before 304 NOT MODIFIED is returned if the value isn't updated |
-
-The timeout can be set to any number of seconds, with a maximum of 600 seconds (10 minutes).
-
-
-**InsertItem: `PUT /<bucket>/<partition key>?sort_key=<sort_key>`**
-
-Inserts a single item. This request does not use JSON, the body is sent directly as a binary blob.
-
-To supersede previous values, the HTTP header `X-Garage-Causality-Token` should
-be set to the causality token returned by a previous read on this key. This
-header can be ommitted for the first writes to the key.
-
-Example query:
-
-```
-PUT /my_bucket/mailboxes?sort_key=INBOX HTTP/1.1
-X-Garage-Causality-Token: opaquetoken123
-
-myblobblahblahblah
-```
-
-Example response:
-
-```
-HTTP/1.1 204 No Content
-```
-
-**DeleteItem: `DELETE /<bucket>/<partition key>?sort_key=<sort_key>`**
-
-Deletes a single item. The HTTP header `X-Garage-Causality-Token` must be set
-to the causality token returned by a previous read on this key, to indicate
-which versions of the value should be deleted. The request will not process if
-`X-Garage-Causality-Token` is not set.
-
-Example query:
-
-```
-DELETE /my_bucket/mailboxes?sort_key=INBOX HTTP/1.1
-X-Garage-Causality-Token: opaquetoken123
-```
-
-Example response:
-
-```
-HTTP/1.1 204 NO CONTENT
-```
-
-### Operations on index
-
-**ReadIndex: `GET /<bucket>?start=<start>&end=<end>&limit=<limit>`**
-
-Lists all partition keys in the bucket for which some triplets exist, and gives
-for each the number of triplets, total number of values (which might be bigger
-than the number of triplets in case of conflicts), total number of bytes of
-these values, and number of triplets that are in a state of conflict.
-The values returned are an approximation of the true counts in the bucket,
-as these values are asynchronously updated, and thus eventually consistent.
-
-Query parameters:
-
-| name      | default value | meaning                                                        |
-|-----------|---------------|----------------------------------------------------------------|
-| `prefix`  | `null`        | Restrict listing to partition keys that start with this prefix |
-| `start`   | `null`        | First partition key to list, in lexicographical order          |
-| `end`     | `null`        | Last partition key to list (excluded)                          |
-| `limit`   | `null`        | Maximum number of partition keys to list                       |
-| `reverse` | `false`       | Iterate in reverse lexicographical order                       |
-
-The response consists in a JSON object that repeats the parameters of the query and gives the result (see below).
-
-The listing starts at partition key `start`, or if not specified at the
-smallest partition key that exists.  It returns partition keys in increasing
-order, or decreasing order if `reverse` is set to `true`,
-and stops when either of the following conditions is met:
-
-1. if `end` is specfied, the partition key `end` is reached or surpassed (if it
-   is reached exactly, it is not included in the result)
-
-2. if `limit` is specified, `limit` partition keys have been listed
-
-3. no more partition keys are available to list
-
-In case 2, and if there are more partition keys to list before condition 1
-triggers, then in the result `more` is set to `true` and `nextStart` is set to
-the first partition key that couldn't be listed due to the limit. In the first
-case (if the listing stopped because of the `end` parameter), `more` is not set
-and the `nextStart` key is not specified.
-
-Note that if `reverse` is set to `true`, `start` is the highest key
-(in lexicographical order) for which values are returned.
-This means that if an `end` is specified, it must be smaller than `start`,
-otherwise no values will be returned.
-
-Example query:
-
-```
-GET /my_bucket HTTP/1.1
-```
-
-Example response:
-
-```json

-
-
-### Operations on batches of items
-
-**InsertBatch: `POST /<bucket>`**
-
-Simple insertion and deletion of triplets. The body is just a list of items to
-insert in the following format:
-`{ pk: "<partition key>", sk: "<sort key>", ct: "<causality token>"|null, v: "<value>"|null }`.
-
-The causality token should be the one returned in a previous read request (e.g.
-by ReadItem or ReadBatch), to indicate that this write takes into account the
-values that were returned from these reads, and supersedes them causally. If
-the triplet is inserted for the first time, the causality token should be set to
-`null`.
-
-The value is expected to be a base64-encoded binary blob. The value `null` can
-also be used to delete the triplet while preserving causality information: this
-allows to know if a delete has happenned concurrently with an insert, in which
-case both are preserved and returned on reads (see below).
-
-Partition keys and sort keys are utf8 strings which are stored sorted by
-lexicographical ordering of their binary representation.
-
-Example query:
-
-```json
-POST /my_bucket HTTP/1.1
-
-[
-  { pk: "mailbox:INBOX", sk: "001892831", ct: "opaquetoken321", v: "b64cryptoblob321updated" },
-  { pk: "mailbox:INBOX", sk: "001892912", ct: null, v: "b64cryptoblob444" },
-  { pk: "mailbox:INBOX", sk: "001892932", ct: "opaquetoken654", v: null },
-]
-```
-
-Example response:
-
-```
-HTTP/1.1 204 NO CONTENT
-```
-
-
-**ReadBatch: `POST /<bucket>?search`**, or alternatively<br/>
-**ReadBatch: `SEARCH /<bucket>`**
-
-Batch read of triplets in a bucket.
-
-The request body is a JSON list of searches, that each specify a range of
-items to get (to get single items, set `singleItem` to `true`). A search is a
-JSON struct with the following fields:
-
-| name            | default value | meaning                                                                                |

-| `partitionKey`  | **mandatory** | The partition key in which to search                                                   |
-| `prefix`        | `null`        | Restrict items to list to those whose sort keys start with this prefix                 |
-| `start`         | `null`        | The sort key of the first item to read                                                 |
-| `end`           | `null`        | The sort key of the last item to read (excluded)                                       |
-| `limit`         | `null`        | The maximum number of items to return                                                  |
-| `reverse`       | `false`       | Iterate in reverse lexicographical order on sort keys                                  |
-| `singleItem`    | `false`       | Whether to return only the item with sort key `start`                                  |
-| `conflictsOnly` | `false`       | Whether to return only items that have several concurrent values                       |
-| `tombstones`    | `false`       | Whether or not to return tombstone lines to indicate the presence of old deleted items |
-
-
-For each of the searches, triplets are listed and returned separately. The
-semantics of `prefix`, `start`, `end`, `limit` and `reverse` are the same as for ReadIndex. The
-additionnal parameter `singleItem` allows to get a single item, whose sort key
-is the one given in `start`. Parameters `conflictsOnly` and `tombstones`
-control additional filters on the items that are returned.
-
-The result is a list of length the number of searches, that consists in for
-each search a JSON object specified similarly to the result of ReadIndex, but
-that lists triplets within a partition key.
-
-The format of returned tuples is as follows: `{ sk: "<sort key>", ct: "<causality
-token>", v: ["<value1>", ...] }`, with the following fields:
-
-- `sk` (sort key): any unicode string used as a sort key
-
-- `ct` (causality token): an opaque token served by the server (generally
-  base64-encoded) to be used in subsequent writes to this key
-
-- `v` (list of values): each value is a binary blob, always base64-encoded;
-  contains multiple items when concurrent values exists
-
-- in case of concurrent update and deletion, a `null` is added to the list of concurrent values
-
-- if the `tombstones` query parameter is set to `true`, tombstones are returned
-  for items that have been deleted (this can be usefull for inserting after an
-  item that has been deleted, so that the insert is not considered
-  concurrent with the delete). Tombstones are returned as tuples in the
-  same format with only `null` values
-

-**DeleteBatch: `POST /<bucket>?delete`**
-
-Batch deletion of triplets. The request format is the same for `POST
-/<bucket>?search` to indicate items or range of items, except that here they
-are deleted instead of returned, but only the fields `partitionKey`, `prefix`, `start`,
-`end`, and `singleItem` are supported. Causality information is not given by
-the user: this request will internally list all triplets and write deletion
-markers that supersede all of the versions that have been read.
-
-This request returns for each series of items to be deleted, the number of
-matching items that have been found and deleted.
-
-Example query:
-
-```json
-POST /my_bucket?delete HTTP/1.1
-
-[
-  {
-    partitionKey: "mailbox:OldMailbox",
-  },
-  {
-    partitionKey: "mailbox:INBOX",
-    start: "0018928321",
-    singleItem: true,
-  },
-]
-```
-
-Example response:
-
-```json
-HTTP/1.1 200 OK
-
-[
-  {
-    partitionKey: "mailbox:OldMailbox",
-    prefix: null,
-    start: null,
-    end: null,
-    singleItem: false,
-    deletedItems: 35,
-  },
-  {
-    partitionKey: "mailbox:INBOX",
-    prefix: null,
-    start: "0018928321",
-    end: null,
-    singleItem: true,
-    deletedItems: 1,
-  },

-
-**PollRange: `POST /<bucket>/<partition key>?poll_range`**, or alternatively<br/>
-**PollRange: `SEARCH /<bucket>/<partition key>?poll_range`**
-
-Polls a range of items for changes.
-
-The query body is a JSON object consisting of the following fields:
-
-| name            | default value | meaning                                                                                |
-|-----------------|---------------|----------------------------------------------------------------------------------------|
-| `prefix`        | `null`        | Restrict items to poll to those whose sort keys start with this prefix                 |
-| `start`         | `null`        | The sort key of the first item to poll                                                 |
-| `end`           | `null`        | The sort key of the last item to poll (excluded)                                       |
-| `timeout`       | 300           | The timeout before 304 NOT MODIFIED is returned if no value in the range is updated    |
-| `seenMarker`    | `null`        | An opaque string returned by a previous PollRange call, that represents items already seen |
-
-The timeout can be set to any number of seconds, with a maximum of 600 seconds (10 minutes).
-
-The response is either:
-
-- A HTTP 304 NOT MODIFIED response with an empty body, if the timeout expired and no changes occurred
-
-- A HTTP 200 response, indicating that some changes have occurred since the last PollRange call, in which case a JSON object is returned in the body with the following fields:
-
-| name            | meaning                                                                                |
-|-----------------|----------------------------------------------------------------------------------------|
-| `seenMarker`    | An opaque string that represents items already seen for future PollRange calls         |
-| `items`         | The list of items that have changed since last PollRange call, in the same format as ReadBatch |
-
-If no seen marker is known by the caller, it can do a PollRange call
-without specifying `seenMarker`. In this case, the PollRange call will
-complete immediately, and return the current content of the range (which
-can be empty) and a seen marker to be used in further PollRange calls. This
-is the only case in which PollRange might return an HTTP 200 with an empty
-set of items.
-
-A seen marker returned as a response to a PollRange query can be used for further PollRange
-queries on the same range, or for PollRange queries in a subrange of the initial range.
-It may not be used for PollRange queries on ranges larger or outside of the initial range.
-
-Example query:
-
-```json
-SEARCH /my_bucket?poll_range HTTP/1.1
-
-{
-  "prefix": "0391.",
-  "start": "0391.000001973107",
-  "seenMarker": "opaquestring123",
-}
-```
-
-
-Example response:
-
-```json
-HTTP/1.1 200 OK
-Content-Type: application/json
-
-{
-  "seenMarker": "opaquestring456",
-  "items": [
-    { sk: "0391.000001973221", ct: "opaquetoken123", v: ["b64cryptoblob123", "b64cryptoblob'123"] },
-    { sk: "0391.000001974191", ct: "opaquetoken456", v: ["b64cryptoblob456", "b64cryptoblob'456"] },
-  ]
-}

-## Internals: causality tokens
-
-The method used is based on DVVS (dotted version vector sets). See:
-
-- the paper "Scalable and Accurate Causality Tracking for Eventually Consistent Data Stores"
-- <https://github.com/ricardobcl/Dotted-Version-Vectors>
-
-For DVVS to work, write operations (at each node) must take a lock on the data table.
