- change the terminology: the network configuration becomes the role table, the configuration of a nodes becomes a node's role - the modification of the role table takes place in two steps: first, changes are staged in a CRDT data structure. Then, once the user is happy with the changes, they can commit them all at once (or revert them). - update documentation - fix tests - implement smarter partition assignation algorithm This patch breaks the format of the network configuration: when migrating, the cluster will be in a state where no roles are assigned. All roles must be re-assigned and commited at once. This migration should not pose an issue.

//! This package provides a simple implementation of conflict-free replicated data types (CRDTs)
|
|
//!
|
|
//! CRDTs are a type of data structures that do not require coordination. In other words, we can
|
|
//! edit them in parallel, we will always find a way to merge it.
|
|
//!
|
|
//! A general example is a counter. Its initial value is 0. Alice and Bob get a copy of the
|
|
//! counter. Alice does +1 on her copy, she reads 1. Bob does +3 on his copy, he reads 3. Now,
|
|
//! it is easy to merge their counters, order does not count: we always get 4.
|
|
//!

//! Learn more about CRDT [on Wikipedia](https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type)
