Kognitio and WX-2 update

I went to Bracknell Wednesday to spend time with the Kognitio team. I think I came away with a better understanding of what the technology is all about, and why certain choices have been made.

Like almost every other contender in the market,* Kognitio WX-2 queries disk-based data in the usual way. Even so, WX-2′s design is very RAM-centric. Data gets on and off disk in mind-numbingly simple ways – table scans only, round-robin partitioning only (as opposed to the more common hash), and no compression. However, once the data is in RAM, WX-2 gets to work, happily redistributing as seems optimal, with little concern about which node retrieved the data in the first place. (I must confess that I don’t yet understand why this strategy doesn’t create ridiculous network bottlenecks.) How serious is Kognitio about RAM? Well, they believe they’re in the process of selling a system that will include 40 terabytes of the stuff. Apparently, the total hardware cost will be in the $4 million range.

*Exasol is the big exception. They basically use disk as a source from which to instantiate in-memory databases.
