> Key: IOTDB-1428
> URL: https://issues.apache.org/jira/browse/IOTDB-1428
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Core/Engine
> Reporter: Tian Jiang
> Assignee: Alima777
> Priority: Major
> Labels: pull-request-available, query, resource-management
> Original Estimate: 16h
> Remaining Estimate: 16h
>
> 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.
