[jira] [Created] (RATIS-850) Allow log purge up to snapshot index

Hanisha Koneru created RATIS-850:
------------------------------------

             Summary: Allow log purge up to snapshot index
                 Key: RATIS-850
                 URL: https://issues.apache.org/jira/browse/RATIS-850
             Project: Ratis
          Issue Type: Improvement
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


Ratis logs are purged only up to the least commit index on all the peers. But if one peer is down, it stop log purging on all the peers. If the Ratis server takes snapshots, then we can purge logs up to the snapshot index even if some peer has not committed up to that index. When the peer rejoins the ring, instead of ratis logs, it can get the snapshot to catch up.
