-----------------------------------------

             Summary: Eliminate buffer copying in SegmentedRaftLogOutputStream
                 Key: RATIS-589
                 URL: https://issues.apache.org/jira/browse/RATIS-589
             Project: Ratis
          Issue Type: Improvement
          Components: server
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze


In SegmentedRaftLogOutputStream.write(LogEntryProto entry), the entry is first converted to a byte array and then write to BufferedWriteChannel.  In BufferedWriteChannel, it copies the byte array to a ByteBuffer.  The copying should be eliminated.
