STOP SLAVE

The terms master and slave have historically been used in replication, but the terms terms primary and replica are now preferred. The old terms are used throughout the documentation, and in MariaDB commands, although MariaDB 10.5 has begun the process of renaming. The documentation will follow over time. See MDEV-18777 to follow progress on this effort.

Syntax

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

STOP ALL SLAVES [thread_type [, thread_type]]

STOP REPLICA ["connection_name"] [thread_type [, thread_type] ... ] -- from 10.5.1

STOP ALL REPLICAS [thread_type [, thread_type]] -- from 10.5.1

thread_type: IO_THREAD | SQL_THREAD

Description

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

Like START SLAVE, 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 SLAVE 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 SLAVE doesn't delete the connection permanently. Next time you execute START SLAVE 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 SLAVE.

STOP ALL SLAVES

MariaDB starting with 10.0

STOP ALL SLAVES 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

MariaDB starting with 10.0

The connection_name option was added as part of multi-source replication added in MariaDB 10.0

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 SLAVE statement will apply to the specified master. connection_name is case-insensitive.

STOP REPLICA

MariaDB starting with 10.5.1

STOP REPLICA is an alias for STOP SLAVE from MariaDB 10.5.1.
