[jira] [Created] (RATIS-410) entry with stateMachineData may cause OOM

Mukul Kumar Singh created RATIS-410:
---------------------------------------

             Summary: entry with stateMachineData may cause OOM
                 Key: RATIS-410
                 URL: https://issues.apache.org/jira/browse/RATIS-410
             Project: Ratis
          Issue Type: Bug
          Components: server
    Affects Versions: 0.3.0
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh


With Ozone, each of raft log segments are of 1GB in size. Also each of the writeChunk request will have 16MB worth of payload. So this can result in multiple writeChunk requests to be part of one log segment.

Because the caching policy in ratis works on eviction of log segments, these results in segments holding onto memory which is part of stateMachine.
