> When a task fails and it is pipelined region failover strategy, all tasks in the region of the failed task and in the downstream regions will be canceled for later re-scheduling. However, these tasks can be still in CREATED state so that there is no need to cancel these tasks. Skipping canceling these tasks can speed up the failover and reduce a lot of unnecessary CANCELING logs.
