> 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.
