---------------------------------
Summary: Ending a query does not terminate it
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: Xiangwei Wei
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.
