You may want to try with the ZODB. Or with SQLite.

Persistant dictionary with lockable elements
Hi, I'd like to have a persistant dictionary in a server so that incoming requests acquire a specific Python object, do something with it then return. There wont be that many objects but it is the persistance that is important here, I want the information to survive server re-starts / crashes. The Shelve module seems ideal for this, but because the server will be multithreaded I would like to be able to lock individual elements of the shelve while they are being processed (not just the entire Shelve object). Is there some way of using Shelve like this, or should I just move to a more typical database solution?
