Aleksandr Polovtcev updated IGNITE-18172:
-----------------------------------------
Ignite Flags: (was: Docs Required)
> Raft learners rebalance
> -----------------------
>
> Key: IGNITE-18172
> URL: https://issues.apache.org/jira/browse/IGNITE-18172
> Project: Ignite
> Issue Type: Task
> Reporter: Aleksandr Polovtcev
> Assignee: Aleksandr Polovtcev
> Priority: Major
> Labels: ignite-3
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Currently, the Rebalance protocol only applies to Raft followers. We would
> like to extend it to be applicable to rebalancing Raft learners as well. The
> following should be done:
> # {{partition.assignments.*}} Metastorage keys should store followers'
> assignments as well as learners' assignments. I propose adding a flag to the
> corresponding entries (i.e. {{isFollower}}).
> # When reacting to changes in Metastorage entries, call a new version of
> `changePeersAsync` (see IGNITE-18155) that will provide new followers and
> learners.
> Concrete applications of learners rebalance and actual learner assignments
> are subject of further design (e.g. it can be used in Metastorage and
> Replicated Tables).
