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

TokyoCabinet:
http://tokyocabinet.sourceforge.net/

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).
