This helps prevent against a case of a connection being terminated on the wrong TiDB server, because it is common to place multiple TiDB servers behind a load balancer. -* Only set [`compatible-kill-query = true`](/tidb-configuration-file.md#compatible-kill-query) in your configuration file if you are certain that clients always will be connected to the same TiDB node, since the default mysql client on ctrl-c will open a new connection to kill the currently running command, and if there are proxies in between, the new connection might be routed to a different TiDB node possibly killing a different session. +* DO NOT set [`compatible-kill-query = true`](/tidb-configuration-file.md#compatible-kill-query) in your configuration file UNLESS you are certain that clients will be always connected to the same TiDB node. This is because pressing ctrl+c in the default MySQL client opens a new connection in which `KILL` is executed. If there are proxies in between, the new connection might be routed to a different TiDB node, which possibly kills a different session. * The `KILL TIDB` statement is a TiDB extension, which is a different syntax from the MySQL `KILL [CONNECTION|QUERY]` command and the MySQL command-line ctrl+c feature. It is safe to use `KILL TIDB` on the same TiDB node. ## See also
