Hi. I had asked this question on zope3 about a week ago or so an had no
responses. I am hoping I can receive some general guidance on this issue.
I am trying to determine the best structure for storing a large schema
where some attributes are lists or dictionaries. There are about 70
attributes in the schema and I am trying to choose a structure that will
not necessarily have to hold a bunch of empty space. I have a base schema
of approximately 30 attributes and others that subclass from it with the
largest being about 70.

How about using Zope BTree datastructures? They are heavily optimized to be used within the ZODB.
