Oh wow, I had no idea Greenplum was being open sourced, that's great news. I fiddled with it 6 years agocomparing it and Vertica for some large scale analytics work and it was pretty impressive.. I wonder how hard to merge Postgres head features back into Greenplum though, or vice versa. Probably not gonna happen?

  It's hard for me to answer you because I work for Pivotal Labs and I've heard stuff in confidence about the current thinking of what to do next. But once it's opensource I think all sorts of possibilities open up legally, technically and economically.

    Are the newer PostgreSQL development been merged back in greenplum, or is it based on an older version? Is the recent Dell acquisition putting the open sourcing plans at risk?

      I'm afraid I couldn't answer these questions even if I knew. Blah blah a lot of it I don't know rhubarb doctrine of confidence murmer cough professional ethics mumble mutter SEC regulations yadda yadda.

That's interesting. 8.x is pretty antique, though; has anything from the 9.x mainline been merged back in? I'd love to hear about a release date, too.

  We announced our opensource plans in February[1]. I don't know when Greenplum will be ready to be opened up, as I work in Labs, which is a different division. So far we have opened Apache HAWQ (incubating)[2], which is an SQL query engine for Hadoop based on the MPP query planner in Greenplum. And Apache Geode (incubating)[3], which is based on Gemfire, which is the most successful in-memory grid database you've never heard of. Edit: I suppose I should mention, entirely in my own self-interest, that we are hiring in our Big Data division across all our products. You can look at our webpage (https://pivotal.io/careers https://pivotal.io/careers) or email me (jchester@pivotal.io).

    Looks like you got GemFire from Gemstone, which is also owned by VMware? That explains why it's written in Java, whereas I was happily surprised that HAWQ is written in C++. It's great that you're releasing stuff as open source. Perhaps you could persuade a colleague at your other division to talk about Greenplum in this thread?

      We (Pivotal) had a bunch of EMC and VMWare companies, technologies and technologies spun into us when the company was founded a few years ago. Including: Cloud Foundry, Greenplum, Spring, Gemfire and of course the namesake -- Pivotal Labs. Email me and I will connect you with our director of engineering for Big Data.
