Starting with release 2011.08.24 the self-proclaimed "cloud database" Drizzle supports real-time messaging through ZeroMQ. Marcus Eriksson, who is also the author of the JDBC driver for Drizzle, has developed the ZeroMQ plugin. Extending the Unix socket API Drizzle can now use ZeroMQ for replication. It's implemented as multi-frame messages, where the first frame contains the name of the database table to be replicated. The second frame contains the data of the serialized transaction.
