I don’t usually post about business deals on my blog. But today’s acquisition of Greenplum by EMC is too close to home not to comment. I’ve been involved as a technical advisor at Greenplum for almost three years, and joined the EMC technical advisory board this spring — so I have some interest in the deal.
Below is my take on things from the technical side. Note that I’m not privy to any private information about the deal, and I’m generally more interested in the tech than the finance. No need to try and read financial tea leaves here — there aren’t any. This is a computer scientist’s view of the technology implications.  Here goes:

The first of two invited posts at GigaOm are up.  These are not researchy, they’re intended to be informative to a broad audience.  They describe the state of affairs in data parallelism, and some of the reasons why this is an increasingly hot topic.

This started out as an exercise for Greenplum, a company I advise that sells a massively parallel DBMS based on PostgreSQL.  I’ve been helping them with their recent launch of a MapReduce interface to their system.  That’s been an interesting project. I’ll write about it more soon.

Along the way, they asked if I’d write a blog post for them about parallelism, SQL and MapReduce to put things into perspective.  I sat down to write a few paragraphs on the subject and ended up with a seven-page essay.  Too long for a blog post so I just turned it into a Tech Report. (a.k.a. a white paper in industrial terms).  We excerpted it for GigaOm to run in a couple posts.  The original is more nuanced and playful, but hey — blogging isn’t about 7-page essays.  I’ll try to control myself here too, and stick with a few paragraphs per post.  And if that causes me to write more tech reports, so be it — I’ll link them in.
