Re: Re: [PyCS-devel] Re: Maybe problems with Metakit 2.4.9.3

I've poked around a bit more and another possibility is ZODB. It can be 
used either as a multi-process database or a multi-threaded single file.

I don't know the internals of PyCS, but it would require a couple of 
changes in PyDS. The biggest change is that ZODB stores Python objects, 
not just class-free database rows. Overall, I think this would be a good 
change anyhow.

It looks to me like you'd need to replace current Metakit functionality 
with an object that would probably sub-class a BTree 
(http://zope.org/Wikis/ZODB/FrontPage/guide/node6.html#SECTION000630000000000000000) 
and also index by other interesting attributes, probably with a simple 
dict (at least for PyDS, PyCS may need other BTrees).
