I see. Verified that "usually" only a fetch is done. Thanks for the
clarification.

So when I load in memory an object with references to 1000 other
persistent objects, 1000 ghost instantes are created. Is that right?.
I'm seeing the code and can't find where those objects are created.
Unless the "ghosted" instances are keept in the pickle of the parent
object, that is.

I'm a bit lost is such a low level view. I would appreciate a low level
description of object loading, in english.

For example:

How can you garantee that if you already have the object in memory, the
ghost creation takes that instance from cache?. Where in the code is
that done?.

Where exactly in the code are referenced ghost objects created?.

Thanks in advance.
