Getting ready

For this recipe, we'll assume that we've set up replication as described in either the Setting up replication or Using multisource replication recipes earlier in this chapter. Pick a master server and a slave server to use. In this recipe, we'll call the master server db01 and the slave server db03.

    binlog_format = row
    replicate_annotate_row_events
    
  3. Restart MariaDB on both servers.

  4. On db01, launch the mysql command-line client and...
