[Zope-dev] ZODB DA?

[Bill Anderson]

OK, this has been rolling around in my head for a while, thought I'd get
it out and take it for a walk.

For many needs, the ZODB fits much better than an RDBMS.
Unfortunately, there are some issues.

Linux x86 32 Bit VFS:
Yes the 2sgb problem. Granted it can be fixed, but I believe there can
be larger issues.

Just Plain Size:
A big Data.fs can be a pain to backup, or to load. You may not
neccesarily want to staore everything in your 'main'  ZODB. Maybe being
able to use a seperate db for seperate uses would be handy, eg. an
inventory that gives you ZODB benefits, but doesn't make your server
'forever' to initialize when it reaches larger sizes? 

I have this feeling it would totally rock.

Does anyone else think this would be cool, or have I just spent too much
time behind the keyboard? :-) It is true ( I think) that it would likely
need a ZODBMethod rather than an SQL method :-(

Of course, continuing the idea can lead to other cool concepts ....
Roxen has the idea of mounted filesystems, such that you can have to
physically seperate filesystems on the machine, mapping under each other
ie. ...

/foo  (is /home/users/foo)
/foo/ftp (is /home/ftp/users/foo)

...and all requests are dealt with accordingly, no Regex'ing needed. It
strikes me as useful that, given the above, one could carry it a step
further, and have a 'directory' be a seperate ZODB. Now, _that_ would be
cool. Alas, I have doubts as to whether this would be a less than
massive undertaking. But I like the idea :-)

As I said, the forst Idea has been percolating in my head for a few
weeks now, had to get it out somewhere :-) ... The second, well, it just
came up ... just random musings ...
