> Key: IGNITE-18394
> URL: https://issues.apache.org/jira/browse/IGNITE-18394
> Project: Ignite
> Issue Type: Epic
> Reporter: Aleksandr Polovtcev
> Assignee: Aleksandr Polovtcev
> Priority: Major
> Labels: ignite-3
>
> We want to use the learner mechanism in MetaStorage, i.e. a learner is started on every Ignite node if it isn't already a voting member of the MetaStorage Group.
> This will allow us to simplify the current implementation in the following ways:
> 1. Get rid of a pull model based on Watchers. Instead all updates will arrive at the Raft listener.
> 2. Simplify MetaStorage Raft storage due to the removal of the Watch functionality.
