This is a group for anyone interested in Greenplum, PostgreSQL, MPP, Open Source, Big Data, Database Development. We will host regular meetup and publish latest news and articles. In addition, we will discuss technique issues/questions using maillist. Greenplum Database is a massively parallel processing (MPP) database server based on PostgreSQL open-source technology. An MPP system is a cluster with two or more PostgreSQL database instances cooperating to accomplish a task, each instance with its own memory and storage. Greenplum Database uses this high-performance system architecture to distribute the load of multi-terabyte data warehouses, and can use all of the system’s resources in parallel to process a query.
