19.1.5.6 Stopping Multi-Source Replicas

The STOP REPLICA statement can be used to stop a multi-source replica. By default, if you use the STOP REPLICA statement on a multi-source replica all channels are stopped. Optionally, use the FOR CHANNEL channel clause to stop only a specific channel.

To stop all currently configured replication channels:
```
mysql> STOP REPLICA;
```
To stop only a named channel, use a FOR CHANNEL channel clause:
```
mysql> STOP REPLICA FOR CHANNEL "source_1";
```

For the full syntax of the STOP REPLICA statement and other available options, see Section 15.4.2.5, “STOP REPLICA Statement”.
