Jialin Qiao commented on IOTDB-4037:
------------------------------------
Worker-Thread is controled by IoTDBConfig.concurrentQueryThread, the default
value could be set to 0 and then related to CPU processors.
pool-13-IoTDB-MPPCoordinator is controled by
IoTDBConfig.coordinatorReadExecutorSize, this could use a separated ThreadPool
instead of the
executor in Coordinator, or be limited to a small number in standalone version.
> [ThreadNum] Compare thread number between start-server.sh and
> start-new-server.sh
