I use FileStorage (via ZEO).
I have switched a big dictionary from PersistentMapping to BTree.
In the past, it was easy to compute added/deleted keys from states (cause
PersistentMapping state contains the whole dictionary,
HistoryJar is what I was looking for !!
Thanks !

Of course not from a single state: it just tells you about the
current keys, not about their history.
If you are using a storage with history
Hi,
I would like to know if from BTree state data, it is possible to compute
which keys were added/deleted.
I need to analyze something in my ZODB and this would really help me.
The complexity of BTree is that not all the dictionary-like data gets
copied in each state.
Thanks a lot for your help.
