Apache9 commented on issue #343: HBASE-22634 : Improve performance of BufferedMutator URL: https://github.com/apache/hbase/pull/343#issuecomment-521163341 Performance is not everything. To be honest, the patch is still not qualified enough to be merged. Please see my last comments, doing busy wait( sleep(1) ) on a critical path is usually a no no, especially that you are waiting for external I/O to complete rather than an in memory operation... Anyway, I got your point that the current implementation of BufferMutator could be optimized to increase the concurrency. Will take a look if I have time. Thanks.
