Thanks for the heads up on HyperDex - I'd missed that. Do you know of a good web reference that tracks new datastore implementations?

I've got the book - its good heads up for someone like me who is mainly working in non DB areas and needs a quick summary of alternatives. I would have liked more on SQL and pre web era data stores.

VoltDB would have been nice. Redis is more interesting to me than most of the NoSQL solutions - as it offers me something different than I can coax an SQL DB into delivering.
