Song Ziyang updated RATIS-1730:
-------------------------------
Description:
Using JProfiler, I found almost 50% of AppendEntriesAsync execution time is
spent on checkAndEvictCache, see the attached pic. There's also a TODO[1]
suggesting to use a daemon thread to perform checkAndEvictCache.
Here are my configurations:
RaftLog SegmentSize: 96MB
RaftLogCache Segment Num Max: 2
RaftLogCache Size Max: 200MB
Am I setting the configurations improperly? If not, we shall use a daemon
thread.
[1][https://github.com/apache/ratis/blob/b8117f41481f5f5861566a68bb1ea4dc7c60320c/ratis-server/src/main/java/org/apache/ratis/server/raftlog/segmented/SegmentedRaftLog.java#L402]
