> Support for snapshot streaming in RAFT state machine
> ----------------------------------------------------
>
> Key: IGNITE-17253
> URL: https://issues.apache.org/jira/browse/IGNITE-17253
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-alpha6
>
>
> In JRaft, snapshotting works through files: first, a snapshot is written to a
> file, later it is sent to follower(s).
> This requires additional FS space, and it is a bit strange for in-memory
> cases.
> We need to switch to streaming way of doing snapshots: when the leader needs
> to bootstrap a follower, it opens a 'channel' to the follower, starts
> producing a snapshot and streaming it to the follower. The follower applies
> the snapshot in the same streaming way.
> This ticket is about modifying JRaft internal infrastructure to switch to
> snapshot streaming.
> See IGNITE-17083
