----------------------------------
Summary: Sync PurgeLog will block WriteLog
Key: RATIS-1596
URL: https://issues.apache.org/jira/browse/RATIS-1596
Project: Ratis
Issue Type: Improvement
Reporter: Song Ziyang
Currently, all RaftLog IO Tasks will be handed to SegmentRaftLogWorker,
including WriteLog & PurgeLog. Since SegmentRaftLogWorker is a single thread, a
time consuming PurgeLog will block the subsequent WriteLog tasks, leading to
follower unable to commit log and respond to leader's AppendEntry RPC.
PurgeLog itself will not affect other IO tasks, is it possible and it can be
done asynchronously by another thread?
