Google fails me. Anything like Python’s ZODB for Ruby? I found madeleine but a prevayler type system isnt really what I’m looking for. Pointers to projects, urls etc would be great. ---

Perhaps DyBase? [http://www.garret.ru/~knizhnik/dybase.html](http://www.garret.ru/~knizhnik/dybase.html) Daniel Brumbaugh K. ---

I am not familiar with the full feature set of ZODB but depending on what you need PStore might be what you are looking for. Basically it’s a transactional wrapper around Marshal. [http://www.ruby-doc.org/stdlib/libdoc/pstore/rdoc/index.html](http://www.ruby-doc.org/stdlib/libdoc/pstore/rdoc/index.html) If your requirements (especially on size) are even looser a simple Hash stored via Marshal in a file might be sufficient.

Basically, I want to get rid of dealing with an RDBMS. We are spending way too much time making the code I’m working on working with the RDBMS when if we had an object store, we could just deal with the actual problems. I really like ruby and am hoping to find something for it as we are at the same time moving away from perl… things I’ve found that would hit the spot… Smalltalk w/ Gemstone/S Python w/ Zeo & ZODB HAppS and of course the rubinius and gemstone mentioned above that I found since I posted the first message. Issue is, RDBMS in question contains something on the order of what would become 8 million objects so far and we are now adding around 150,000 more a month so just any old thing obviously wont do. ---
