If the sources in the multi-source replication topology have existing data, it can save time to provision the replica with the relevant data before starting replication. In a multi-source replication topology, cloning or copying of the data ...

Once you have added channels for all of the replication sources, issue a START REPLICA statement to start replication. When you have enabled multiple channels on a replica, you can choose to either start all channels, or select a specific channel ...
https://dev.mysql.com/doc/refman/8.4/en/replication-multi-source-stop-replica.html
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 ...

You can also use a PRIVILEGE_CHECKS_USER account to secure the two replication applier threads used by Group Replication. The group_replication_applier thread on each group member is used for applying group transactions, and the ...

If you use a combination of database-level and table-level replication filtering options, the replica first accepts or ignores events using the database options, then it evaluates all events permitted by those options according to the table options. It is also important to note that the results vary depending on whether the operation is logged using statement-based or row-based binary logging ...

The replica checks for and evaluates table options only if either of the following two conditions is true: No matching database options were found. One or more database options were found, and were evaluated to arrive at an “execute” condition ...

To guarantee the integrity of the files that are copied, backing up the raw data files on your MySQL replica should take place while your replica server is shut down. If the MySQL server is still running, background tasks may still be updating the ...

Note The instructions in this section place the server to be backed up in a state that is safe for backup methods that get the data from the server, such as mysqldump (see Section 6.5.4, “mysqldump — A Database Backup Program”). You should not ...

It does not matter for the replication process whether the original table on the source and the replicated table on the replica use different storage engine types. This provides a number of benefits in the replication process in that you can take ...
https://dev.mysql.com/doc/refman/8.4/en/replication-solutions-scaleout.html
You can use replication as a scale-out solution; that is, where you want to split up the load of database queries across multiple database servers, within some reasonable limitations. Because replication works from the distribution of one source to ...
