Alex	77e3fd6db2	improve internal item counter mechanisms and implement bucket quotas (#326) ... - [x] Refactoring of internal counting API - [x] Repair procedure for counters (it's an offline procedure!!!) - [x] New counter for objects in buckets - [x] Add quotas to buckets struct - [x] Add CLI to manage bucket quotas - [x] Add admin API to manage bucket quotas - [x] Apply quotas by adding checks on put operations - [x] Proof-read Co-authored-by: Alex Auvolat <alex@adnab.me> Reviewed-on: #326 Co-authored-by: Alex <alex@adnab.me> Co-committed-by: Alex <alex@adnab.me>	2022-06-15 20:20:28 +02:00
Alex	b44d3fc796	Abstract database behind generic interface and implement alternative drivers (#322) ... - [x] Design interface - [x] Implement Sled backend - [x] Re-implement the SledCountedTree hack ~~on Sled backend~~ on all backends (i.e. over the abstraction) - [x] Convert Garage code to use generic interface - [x] Proof-read converted Garage code - [ ] Test everything well - [x] Implement sqlite backend - [x] Implement LMDB backend - [ ] (Implement Persy backend?) - [ ] (Implement other backends? (like RocksDB, ...)) - [x] Implement backend choice in config file and garage server module - [x] Add CLI for converting between DB formats - Exploit the new interface to put more things in transactions - [x] `.updated()` trigger on Garage tables Fix #284 **Bugs** - [x] When exporting sqlite, trees iterate empty?? - [x] LMDB doesn't work **Known issues for various back-ends** - Sled: - Eats all my RAM and also all my disk space - `.len()` has to traverse the whole table - Is actually quite slow on some operations - And is actually pretty bad code... - Sqlite: - Requires a lock to be taken on all operations. The lock is also taken when iterating on a table with `.iter()`, and the lock isn't released until the iterator is dropped. This means that we must be VERY carefull to not do anything else inside a `.iter()` loop or else we will have a deadlock! Most such cases have been eliminated from the Garage codebase, but there might still be some that remain. If your Garage-over-Sqlite seems to hang/freeze, this is the reason. - (adapter uses a bunch of unsafe code) - Heed (LMDB): - Not suited for 32-bit machines as it has to map the whole DB in memory. - (adpater uses a tiny bit of unsafe code) **My recommendation:** avoid 32-bit machines and use LMDB as much as possible. **Converting databases** is actually quite easy. For example from Sled to LMDB: ```bash cd src/db cargo run --features cli --bin convert -- -i path/to/garage/meta/db -a sled -o path/to/garage/meta/db.lmdb -b lmdb ``` Then, just add this to your `config.toml`: ```toml db_engine = "lmdb" ``` Co-authored-by: Alex Auvolat <alex@adnab.me> Reviewed-on: #322 Co-authored-by: Alex <alex@adnab.me> Co-committed-by: Alex <alex@adnab.me>	2022-06-08 10:01:44 +02:00

Alex	b490ebc7f6	Many improvements on ring/replication and its configuration: ... - Explicit "replication_mode" configuration parameters that takes either "none", "2" or "3" as values, instead of letting user configure replication factor themselves. These are presets whose corresponding replication/quorum values can be found in replication/mode.rs - Explicit support for single-node and two-node deployments (number of nodes must be at least "replication_mode", with "none" we can have only one node) - Ring is now stored much more compactly with 256*8 + n*32 bytes, instead of 256*32 bytes - Support for gateway-only nodes that do not store data (these nodes still need a metadata_directory to store the list of bucket and keys since those are stored on all nodes; it also technically needs a data_directory to start but it will stay empty unless we have bugs)	2021-05-28 14:07:36 +02:00
