Hanisha Koneru commented on RATIS-850: -------------------------------------- Snapshots are a function of the StateMachine. So they should ideally be kept independent from RaftServer logs. But I see your point. Let's purge upto snapshotIndex, if PURGE_UPTO_SNAPSHOT_INDEX is set to true, irrespective of commitIndex. I will update the patch. > 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 > Priority: Major > Attachments: RATIS-850.001.patch, RATIS-850.002.patch > > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
