> After sending pages, the thread will hold the storage manager write lock and send synchronization finished packet(use the parent thread pool) to the backup node. At the same time, thread pool is full bcs they are waiting for the storage manager read lock to write the page or journal, leading to replication starting failure. Here we use io executor to send replicate packet to fix thread pool starvation problem.
