Hi, I am author of MapDB; database engine which provides Maps, Sets, Queues and other collections backed by disk (or in-memory) storage. MapDB is probably the fastest java db engine, it can do 2 million inserts per second etc...
I read your design paper and it seems we have common goal (high performance persistence). Maybe we could cooperate and share some code. More details about MapDB: https://github.com/jankotek/mapdb Regards, Jan Kotek
