LevelDB in Java
This is a rewrite (port) of Memcached in Java. This goal was to have a feature complete implementation that is within 10% of the performance of the C original.
I started working on this a few years ago and got the slab allocator and hash working, but life being as it is, I never finished the protocol port. If there is general interest in this project, I'd we willing to pick it up again and finish it.
