Sijie Guo created BOOKKEEPER-527:
------------------------------------

             Summary: multiple threads for topic op queuer.
                 Key: BOOKKEEPER-527
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-527
             Project: Bookkeeper
          Issue Type: Improvement
          Components: hedwig-server
            Reporter: Sijie Guo
             Fix For: 4.3.0


currently there is only one single thread scheduler shared across topic manager, subscription manager and bookkeeper manager (also region manager). if enqueue speed is faster than dequeue speed for per topic, lots of operations would be submitted to this single thread scheduler, which cause lots of operations are pending in the executor to execute.

we need to adapt a multiple thread executor of this case. and it would be better to separate executors between managers.
