Yeah, I checked pytables out and it really is a good solution, but the
parts I don't like are the complexity of the install, and no explicit
division of memory and disk based files. The latter is not so
important, but the former is a problem.
As far as mapping to SQL, I handle all the type conversion since I'm
making database tables and flat files transparent. I would only be
using a small subset of the functionality in pytables, which is OK, but
I've done the install on Windows and it's really difficult because of
all the dependencies. It would be easier on Unix though.
I don't know, I'll have to think about it some more. I sure wish there
were better object serialization solutions for Python. Actually I wish
Metakit just supported large files on 32 bit platforms. There simply
aren't enough 64 bit platform to justify requiring users to use one if
they have large tables.

The file size limit is dependent on your OS. If you have a 64 bit

You might want to take a look at pytables which is very metakit-like
in some respects
http://pytables.sourceforge.net/html/WelcomePage.html
I'm not sure how well it maps to sql though.

Crap, well, it looks like unicode might be more accessible in Metakit,
but because of the 2GB file limit, I'd better stick with BSDDB. I can
handle decimals in the same way in both as well.
Thanks for the input. Are there plans to increase the file size limit
soon?

I don't think that having 'b' store unicode would be that difficult
to implement.
