Billy Newport of IBM sees a lot of similarities between his app-server-based product ObjectGrid and H-Store. In both cases, constrained tree schemas are assumed, and OLTP performance goodness ensues. A couple of points I noted on a quick skim through his blog:
- He calls out RAM consumption as a challenge for this kind of architecture.
- He points out that it’s a big advantage to have data called and used in the same address space.
Being based in RAM is obviously a huge part of the H-Store scheme. But so is having transaction execution be close to the database.
IBM now has both ObjectGrid and a memory-centric DBMS (solidDB) that they’ve been using as a front end for DBMS. Integration of the two could be pretty interesting.

I wrote yesterday about the H-Store project, the latest from the team of researchers who also brought us C-Store and its commercialization Vertica. H-Store is designed to drastically improve efficiency in OLTP database processing, in two ways. First, it puts everything in RAM. Second, it tries to gain an additional order of magnitude on in-memory performance versus today’s DBMS designs by, for example, taking a very different approach to ensuring ACID compliance.
Today I had the chance to talk with two more of the H-Store researchers, Sam Madden and Daniel Abadi.

Last week, Dan Weinreb tipped me off to something very cool: Mike Stonebraker and a group of MIT/Brown/Yale colleagues are calling for a complete rewrite of OLTP DBMS. And they have a plan for how to do it, called H-Store, as per a paper and an associated slide presentation.
