Tungsten Core Projects

Tungsten Replicator
Implements database-neutral, master/slave replication.  Tungsten Replicator has a flexible architecture that allows rapid addition of new database types. Robert Hodges' blog on Replicator: http://scale-out-blog.blogspot.com/2008/08/answering-montys-challenge-advanced.html.
Tungsten Manager
Group-communication based framework for managing cluster resources.  Tungsten Manager offers broadcast commands and effecient management of groups of JMX-enabled network services as well as operating system processes.
Tungsten Connector
A powerful proxy for MySQL and PostgreSQL client programs.  The Connector converts native wire protocol requests to JDBC calls and serves as a "front door" to clustering logic implemented in JDBC drivers. Robert Hodges' blog on Tungsten Connector: http://scale-out-blog.blogspot.com/2008/05/myosotis-connector-fast-sql-proxy-for.html.
Tungsten SQL-Router
A JDBC wrapper that adds high-performance and transparent failover, load-balancing, and partitioning to native JDBC drivers.  The SQL Router uses an innovative dispatch mechanism to assign database connections based on application requirements for data consistency and availability. Robert Hodges' blog on SQL Router: http://scale-out-blog.blogspot.com/2009/03/implementing-relaxed-consistency.html.
Tungsten Monitor
A pluggable monitoring service that checks and broadcasts state of individual resources in the cluster.  The Tungsten Monitor supplies up-to-date data required for administration and SQL routing to work efficiently and correctly. Robert Hodges' blog on Tungsten Monitor: http://scale-out-blog.blogspot.com/2009/03/announcing-tungsten-monitor.html.
