The backend of knowtu is a log structured file with MVCC capabilities. Needing high performance for IO; I’ve been using java NIO. I’ve played with java NIO a little, but this is something else. Anyway google search turned up a version of Oreilly’s java nio via google books, I searched through and seemed just the level of detail I needed and well written. I figured for $58 (PDF + Book + international shipping ($20!)) was going to save me an hour so a worth while buy. I still think books are the best for detailed technical usage and best practice information. Given this wasn’t available a few years ago I really like this approach of being able to arbitrarily browse the contents enough to make the decision to buy, so thanks Google, Oreilly and Ron Hitchens.
