-----------------------------------------
Assignee: Tsz Wo Nicholas Sze
> FinalizeLogSegment should flush the contents of log
> ---------------------------------------------------
>
> Key: RATIS-587
> URL: https://issues.apache.org/jira/browse/RATIS-587
> Project: Ratis
> Issue Type: Bug
> Components: LogService
> Reporter: Supratim Deka
> Assignee: Tsz Wo Nicholas Sze
> Priority: Major
>
> SegmentedRaftLog uses a BufferedWriteChannel for writing the log.
> FinalizeLogSegment task is enqueued when a segment fills up. This task closes
> the channel and does cleanup.
> SegmentedRaftLogOutputStream.close() internally invokes
> BufferedWriteChannel.flush(false)
> the false passed to flush indicates not to flush the buffer cache.
> This means that the contents of the log file are not persisted on disk. An
> abrupt power failure could result in loss of committed log entries.
