[GitHub] [iotdb] JackieTien97 opened a new pull request #2596: Improve flush pipeline
JackieTien97 opened a new pull request #2596:
URL: https://github.com/apache/iotdb/pull/2596
There are lots of synchronized methods in PublicBAOS which are unnecessary, because we have ensure the thread-safe property in upper-layer logic. Actually, the call of synchronized methods in ioTask of flush pipeline will cause the encoding task of flush pipeline to be slower. This may ve incurred by the implementation of synchronized key word in java. The encoding task will set the biased lock on, but the ioTask will revert the biased lock and change it to lightweight lock which may afffect the encoding thread, because the lock change process must be executed in a global safe point.
