Kill Query
Kill connection
In Doris, each connection runs in a separate thread. You can terminate a thread using the KILL processlist_idstatement.
The processlist_id for the thread can be found in the Id column from the SHOW PROCESSLIST output. Or you can use the SELECT CONNECTION_ID() command to query the current connection id.
Syntax:
KILL [CONNECTION] processlist_id
Kill query
You can also terminate the query command under execution based on the processlist_id or the query_id.
Syntax:
KILL QUERY processlist_id | query_id
Example
- Check the current connection id.
mysql select connection_id();
+-----------------+
| connection_id() |
+-----------------+
| 48 |
+-----------------+
1 row in set (0.00 sec)
- Check all connection id.
mysql SHOW PROCESSLIST;
