[ZODB-Dev] Nested BTrees?

[Andreas Jung]

I got some sources where an XML document is mapped to a hierarchy
of corresponding objects inside the ZODB (up to some hundred or thousand
objects). The disavantage is clear: it takes very long to create the
hierarchy. I am thinking about an efficient way to keep the object
hierachy inside a single Zope object as nested BTree structure.
Does the ZODB store the complete datastructure (with nested BTrees)
when changing a single BTree of the datastructure or does store only the
changed BTree?
