-For example, the above query generates 2 MPP Tasks on each TiFlash node, where the MPP Task containing `ExchangeSender_45` depends on the MPP Task containing `ExchangeSender_21`. In high concurrency scenarios, if the scheduler schedules the MPP Task containing `ExchangeSender_45` for each query, the system will enter a deadlock state.

 To avoid deadlock, TiFlash introduces the following two levels of thread limits:
