### KILL command support
The MySQL client protocol now detects `KILL <thread_id>` statements (binary and
query forms) and kills the MaxScale session with the given id. This feature has
some limitations, see [Limitations](../About/Limitations.md) for more
information.
The MySQL client protocol now supports execution of `KILL` statements through
MaxScale. The connection IDs in these queries will be transformed into the
correct ones by MaxScale.
`KILL QUERY ID <query_id>` is not supported by MaxScale and it needs to be
executed directly on the relevant backend server. In addition to this, there are
minor limitations to the `KILL` command handling. See
[Limitations](../About/Limitations.md) for more information.
