Greenplum is the first open source Massively Parallel Processing (MPP) data warehouse, built with over two million lines of code. MPP allows a program to run across multiple processors that each use their own memory and operating system. Greenplum was released under Apache software and differs functionally and architecturally from other open source data systems through its use of MPP to execute complex SQL analytics over large datasets at high speeds. As an open source system, Greenplum assures customers that their software needs will be met long-term.
