Using the no-DB approach is particularly tempting with a language like Clojure. Clojure can slice & dice collections easily and efficiently. It has built-in constructs for managing concurrency safely.
I actually have a couple Clojure apps that rely on a hefty amount of in-memory data to do some computations. Even the cost of pulling the data from Redis would be too expensive. The in-memory data grows very slowly, so it's easy to maintain. Moving faster-growing data in-process would be trickier, but this article makes me want to try.
