STOP SLAVE statement can be used to stop
a multi-source replication slave. By default, if you use the
STOP SLAVE statement on a multi-source
replication slave all channels are stopped. Optionally, use the
clause to stop only
a specific channel.
To stop all currently configured replication channels:
STOP SLAVE thread_types;
To stop only a named channel, use a
STOP SLAVE thread_types FOR CHANNEL channel;
thread_types option to choose
specific threads you want the above statements to stop on the
slave. See STOP SLAVE Syntax for more information.
