Tungsten Replicator is a data replication engine for MySQL which is able to replace MySQL's native replication. It provides features such as global transaction IDs (allowing for seamless failover), flexible transaction filtering, extensible transaction metadata, sharding, multiple replication services per process and heterogeneous replication from MySQL to other database systems such as Oracle, MariaDB, MongoDB and PostgreSQL. The project is supported by Continuent, which also offers an Enterprise version. The source code can be found on Google Code: http://code.google.com/p/tungsten-replicator.
