FLUSH PRIVILEGES

This statement triggers TiDB to reload the in-memory copy of privileges from the privilege tables. You should execute FLUSH PRIVILEGES after making manual edits to tables such as mysql.user. Executing this statement is not required after using privilege statements such as GRANT or REVOKE. Executing this statement requires the RELOAD privilege.
