The Ultimate Guide to High Availability with MariaDB

STOP REPLICA

The terms master and slave have historically been used in replication, and MariaDB has begun the process of adding primary and replica synonyms. The old terms will continue to be used to maintain backward compatibility - see MDEV-18777 to follow progress on this effort.

Syntax

STOP REPLICA ["connection_name"] [thread_type [, thread_type] ... ] [FOR CHANNEL "connection_name"]

STOP ALL REPLICAS [thread_type [, thread_type]]

STOP REPLICA ["connection_name"] [thread_type [, thread_type] ... ]

STOP ALL REPLICAS [thread_type [, thread_type]] 

thread_type: IO_THREAD | SQL_THREAD

Description

Stops the replica threads. STOP REPLICA requires the SUPER privilege, or, from MariaDB 10.5.2, the REPLICATION SLAVE ADMIN privilege.

Like START REPLICA, this statement may be used with the IO_THREAD and SQL_THREAD options to name the thread or threads to be stopped. In almost all cases, one never need to use the thread_type options.

STOP REPLICA waits until any current replication event group affecting one or more non-transactional tables has finished executing (if there is any such replication group), or until the user issues a KILL QUERY or KILL CONNECTION statement.

Note that STOP REPLICA doesn't delete the connection permanently. Next time you execute START REPLICA or the MariaDB server restarts, the replica connection is restored with it's original arguments. If you want to delete a connection, you should execute RESET REPLICA.

STOP ALL REPLICAS

STOP ALL REPLICAS stops all your running replicas. It will give you a note for every stopped connection. You can check the notes with SHOW WARNINGS.

connection_name

The connection_name option is used for multi-source replication.

If there is only one nameless master, or the default master (as specified by the default_master_connection system variable) is intended, connection_name can be omitted. If provided, the STOP REPLICA statement will apply to the specified master. connection_name is case-insensitive.

MariaDB starting with 10.7.0

The FOR CHANNEL keyword was added for MySQL compatibility. This is identical as using the channel_name directly after STOP REPLICA.

  • CHANGE MASTER TO is used to create and change connections.
  • START REPLICA is used to start a predefined connection.
  • RESET REPLICA is used to reset parameters for a connection and also to permanently delete a master connection.
