Hi, I am proud to announce stable release of JDBM2. It is 1.0 fork which adds lot of stuff, most notably: * java.util.Map view to indexes * soft cache * secondary map (aka foreign indexes in SQL) * better speed * defragmentation * more space efficient * under Apache 2 license.
However it does not solve biggest problem you had with 1.0. There is still 'big lock' and concurrency access does not scale well. Readonly access is very fast, thanks to soft cache. API and file store format are similar, but incompatible with 1.0 http://code.google.com/p/jdbm2/ http://www.kotek.net/blog/jdbm2_released Regards, Jan Kotek
