Sequoia is the continuation of the C-JDBC project under an Apache license. A new stable production release is available. You can download both binary or source distribution and documentation at Forge site.


C-JDBC is an open source (LGPL) database cluster middleware that allows any Java application (standalone application, servlet or EJB container, ...) to transparently access a cluster of databases through JDBC(tm). The database is distributed and replicated among several nodes and C-JDBC balances the queries among these nodes. C-JDBC handles node failures and provides support for checkpointing and hot recovery.

Sequoia is a new version of C-JDBC available under an Apache license. You can download Sequoia from the Forge.
