I came across an annoucement that Gemstone is working with the  
rubinius crew on a persistence system based on Gemstone/S which would  
be well...
better than anything I was hoping before. 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.
