handling really large collections of mapped child objects

[Laran Evans <lc...@cornell.edu>]

I have a parent object which owns a collection. The objects in the
collection are mapped in ojb. However, the parent may own 10K or more
of the child objects. Thus, the collection may be 10K elements or more
in size. The child objects each hold references to other mapped
objects. Clearly loading the initial parent object would blow up the
system. So, I'm trying to figure out a way to load the parent object
but load the collection in batches.

Is there any mechanism in OJB to do anything similar to this? Does OJB
do anything inherently, or can it be made to do so with customization
to handle really large collections?

I can write custom Query calls if needed. I'd like to stick with as
simple a solution as possible.
