> When a query is ended by closing its belong statement or connection, the query is not terminated as it will be when being killed, so the query may keep running to fetch the first batch of result, which may take a long time when the query is quite large. Moreover, as ending a query removes it from the timeout queue, the ended query is no longer controlled by timeout, thus it may run arbitrarily long.
> So if a query is ended, it should also be terminated as if it is killed to release the resources ASAP.
