You can now replicate data from MySQL data to MongoDB using Tungsten Replicator, an open source data replication engine for MySQL. It’s sponsored by Continuent, makers of Tungsten Enterprise.
The new functionality was added by Continuent CTO Robert Hodges, Flavio Percoco Premoli of The Net Planet and Continuent employee Stephane Giron as part of a hackathon at the Open DB Camp in Sardinia.
Hodges has written a blog post explaining the process of creating the integration. Hodges describes the post as a cookbook for both adding new databases implementations to Tungsten Replicator and setting up MongoDB replication.
