Clustering system of PostgreSQL that is using shared data

PGCluster-II is a shared-disk based clustering system for PostgreSQL, implemented with virtual IPC for session and lock management. It supports both high availability and load balancing needs.

For the past 8 years, Atsushi Mitani has developed a number of web applications which were used PostgreSQL as the backend database. To support high availability for these sites, he developed PGCluster, a multi-master and synchronous replication system for PostgreSQL.

However, PGCluster did not help with load-balancing data writes and new web applications are more write-intensive, as well as requiring more links between disparate data in the database. PGCluster-II is engineered to support load balancing and high availability for this new generation of web applications.

Atsushi will explain how PGCluster is designed and show you how to install and test it.
