What is Tungsten Connector?

Tungsten Connector is a proxy that translates MySQL and PostgreSQL native client requests to JDBC calls.  The Connector works by parsing the native wire protocol and issuing a corresponding JDBC request.  It then translates the response back to the native wire protocol and returns it to the client.  From the client application point of view the Tungsten Connector acts as a MySQL or a PostgreSQL server.

The Tungsten Connector was originally developed to allow MySQL and PostgreSQL clients to connect directly to a Sequoia cluster. It was originally named Myosotis, which is the scientific name of the forget-me-not flower.  

The Tungsten Connector is a robust and useful piece of software. Though written in Java (or rather because of it) the Connector out-performs most other SQL proxies we have tested.  It is the basis for the Continuent uni/cluster Connector, which is a commercial product.
