For those old timers who did distributed systems work there's not that much new under the sun. I look at something like this and say "ah, a quirky and somewhat dangerous cache layer." What's different is bloggers promoting it as a "database."

While I'm sure someone out there will see this and say "wow, that's exactly what I need!" chances are that if you have these sorts of scale issues you're going to have to figure it out on your own.

I'd rather see a write-up of how they arrived at this particular conclusion than another non-database.
