Continuent delivers a GA version of uni/cluster Connector for PostgreSQL. The uni/cluster Connector is a key part of the Continuent vision of transparent database clustering using off-the-shelf databases and commodity hardware. The Connector allows applications that use native database APIs to connect directly to Continuent uni/cluster without changing libraries or making code alterations.
This makes database clustering deployments simpler and faster -- customers can focus on deploying the cluster and just switch client connections when they are ready to move. Another great feature of the Connector is that standard database clients such as psql¹ can work directly with the cluster. So users preserve not only current client applications but also can continue to use familiar administrative tools as well. Finally, the uni/cluster Connector is *fast* and consumes few system resources. It minimizes resource impact of deploying Continuent uni/cluster in new environments. This version of uni/cluster Connector supports all API calls except for use of prepared statements. We are working on these now and expect to provide support in the next release. We are also working on some exciting new Connector features that customers will find useful for building highly scalable database clusters. We invite you to try the Connector and stay tuned for more developments!

No more long failover times and or inconsistent data. If a database server fails, it is automatically removed from the cluster, all users will be reconnected to another database server, and any in-flight transactions are automatically restated. Continuent accomplishes this real-time and without manual intervention. * Fully transparent failover for all transactions * Even transactions that were in-flight during a failure event. This is automatic continuity at the transaction level. No lost transactions and users left looking at error messages or needing to restart their transactions. This helps you avoid lost business due to database outages, which translates to business continuity. Your application no longer has to contain special error processing for this condition. All data will be left in a correct and consistent state. Continuent provides a true-self healing capability from the applications¹ view of the database tier. * Full scale-out capabilities * Scale your database vertically by adding low cost commodity hardware, scale horizontally by data partitioning. In this way, scalability is provided both for queries that are reading the data and queries that create or update data. Flexible load balancing capabilities insure the effective use of your hardware investment.
