> 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.
