Ripple: A Middleman Server for MySQL Replication


Ripple is a server that can serve as a middleman in MySQL replication.

The Ripple server connects to a MySQL master the same way a replica would, but rather than creating a copy of the data in MySQL, Ripple just downloads the binlogs and saves them locally. MySQL servers can then be directed to replicate from Ripple instead of the master. Ripple will serve downloaded binlogs to them the same way the master would. This can significantly reduce load on the MySQL master and improve durability of the binlogs.

Ripple supports replication to/from MariaDB and MySQL using GTIDs (of MariaDB and MySQL flavor respectively). Replication using filename and position is not supported. Ripple has been tested with MariaDB 10.0 and MySQL 5.6 and 5.7, but it likely will work with later versions as well.
