mingchao zhao updated RATIS-1534:
---------------------------------
Description:
In our previous test([see streaming test
doc|https://docs.google.com/document/d/1mS3GqovQ3D1b7V0L3--VF9xhl5jdId1mSL0cQNb7uHo/edit]),
we found that SegmentedRaftLogWorker writing RaftLog seriously affected the
performance of streaming. Mainly because the flush action was very frequent.
So we can change flush to async. This will greatly improve performance. Of
course we'd better make this configurable, which is disable by default.
