Tungsten SQL Router Roadmap

The initial release of the SQL Router supplies key features to allow applications to rout SQL with a minimum of changes and integrate efficiently with other Tungsten components

• Simple configuration and integration with applications
• Pluggable connection routing with support for strict consistency, session consistency, and relaxed consistency
• Pluggable resource notifications with support for data source status updates through UDP and group communications
  
• Tested integration with Tungsten Monitor
  
• JMX management API and accompanying management client
• Support for client connection listeners to enable smooth failover
• Full certification against MySQL
  

Our goal is to keep the SQL Router relatively lightweight but add useful capabilities that get users as close as possible to the goal of making a cluster of databases look like a single database.  Here are some candidates for future releases.

• Better management capabilities
  
• Improved plug-in interfaces
• Support for semi-synchronous commit, where clients get a response after transactions are known to have reached one or more replicas
  
• SQL-level routing based on examination of individual commands
