Mikio Hirabayash released his TokyoCabinet DB. So I took a minute this morning to play around with it!

TokyoCabinet:

My morning's hack:
http://hg.tangent.org/TokyoEngine

I had to modify his engine to make this work. There were no C++ declaration around the include headers, and the tokyocabinet.pc file has a dangling variable in its libs.
I know nothing about performance at the moment... this was just me playing around for a bit. Tokyo Cabinet is his successor to QDBM and the work was sponsored by Mixi.jp (aka... think Facebook for Japan fro the ones of you who never study what the rest of the world is doing).

This stuff is pretty easy for me to write, and the TokyoCabinet code is very easy to follow. You are looking at less then two hours of my time putting together engines does not really take a lot out out me.
