Implement a parallel replication mode that works with a MySQL master

    XMLWordPrintable

Details

    Description

      Many users who want to migrate from MySQL to MariaDB start off by migrating one or more slaves to MariaDB. Right now, all parallel replication modes in MariaDB require the master to be running MariaDB 10.0 or greater. This limitation means that these users cannot use parallel replication until they can also migrate their masters to MariaDB, so the only option until then would be to use serial replication. If the slave lag is too high when using serial replication, some of these users might hold off on or abandon their migration to MariaDB.

      Would it be feasible to implement a parallel replication mode that works with a MySQL master?
