 + Default value: `true`
 + When the value is `true`, both `KILL` and `KILL TIDB` statements can terminate queries or connections across instances so you do not need to worry about erroneously terminating queries or connections. When you use a client to connect to any TiDB instance and execute the `KILL` or `KILL TIDB` statement, the statement will be forwarded to the target TiDB instance. If there is a proxy between the client and the TiDB cluster, the `KILL` and `KILL TIDB` statements will also be forwarded to the target TiDB instance for execution. Currently, using the MySQL command line <kbd>ctrl</kbd>+<kbd>c</kbd> to terminate a query or connection in TiDB is not supported when `enable-global-kill` is `true`. For more information on the `KILL` statement, see [KILL](/sql-statements/sql-statement-kill.md).
