Merv Adrian writes about VoltDB, who recently announced more about what they’re doing, in VoltDB – DIY OLTP. Open Source. Win. VoltDB runs completely in memory, scales on multiple nodes, but only supports a limited set of ANSI SQL. Any missing functions can be added through a fast Java API, hence DIY. They’re lead by Mike Stonebraker, Postgres, Ingres and Vertica co-founder.
