has announced the general availability of p/cluster
, a high availability solution for PostgreSQL
. It integrates seamlessly with any Java application (or app server) as if it were using a single PostgreSQL instance. No application changes are required, just the datasource definition has to be configured with a new JDBC URL.
The clustering features offer high availability with transparent failover and load balancing.
p/cluster is based on the Sequoia
open source technology formerly known as C-JDBC
. Sequoia is a generic ANSI SQL clustering technology based on JDBC. Sequoia 2.6 has been released on Continuent.org
. New features include transparent user management, support for foreign keys, parallel recovery properly scheduling queries to respect foreign key constraints, support for transparent failover with automatic retrieval of last results on write requests, commit, and rollback. Support has also been added for automatic recovery log resync and some new experimental features include semantic support for stored procedures.
