[ZODB-Dev] New to ZODB, how to make a db efficently?

[Jean Jordaan]

Hi Markus

I'll try with some easy answers that won't help you much ;-)

> What makes a physical structure physical? (If I point to the same persistent
> objects from different BTrees, which one then is physical if I store them?)

The first one stored.

> Should I always use an appropriate BTree to store a big mapping? (Becuse the
> BTree isn't loaded at once)

Yes, particularly for a big flat mapping (e.g. a folder containing
many many items).

> How do indexes basically work or how they are made? (Are they also BTrees,
> so that if they are big, they won't load at once?)

Yes they are BTrees.
