MySQL compatibility

  • By design, this statement is not compatible with MySQL by default. 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.
  • The KILL TIDB statement is a TiDB extension. If you are certain that the session you are attempting to kill is on the same TiDB server, set compatible-kill-query = true in your configuration file.
