Kill the connection on the specified thread. Rolls back any query running on the thread.
KILL [CONNECTION | QUERY] <internal_process_id>;
internal_process_id- ID of the thread to kill, which can be found by running SHOW_PROCESSLIST.
KILL CONNECTIONWill disconnect the client associated with
internal_process_id. This is the default, meaning that running
KILL <>will have the same result.
KILL QUERYWill not disconnect the client associated with
internal_process_id. Instead, the client will receive an error.
- Any query running on the connection will be rolled back.
- MemSQL checks for the kill bit during any potentially long running loop during query execution and rolls back the query’s transaction if the kill bit is set.
- This command must be run on the same node as the query to be killed.
- This command should be run on the master aggregator or a child aggregator node (see Node Requirements for MemSQL Commands).
