> Earlier detection of task failure would improve ultimately query response
> time in long-running queries. The objective of this issue is to implement the
> periodical task checker to detect task failure due to ping timeout.
> When the checker detects the ping timeout, it should trigger some event and
> send the event to the corresponding task.
