Are you wondering what this is about or why this matters? Pivotal announced earlier this year that all products will be made open source. Pivotal already has many open source projects like Spring, Cloud Foundry, Gemfire, Redis, Open Data Platform, and Madlib but this will be expanded to include Greenplum Database and HAWQ.

HAWQ is already the fastest and most SQL compliant SQL on Hadoop offering in the market but not it will also be open source! This is a great thing for the Hadoop community as HAWQ is a very powerful tool for the Hadoop ecosystem.
