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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
