[ZODB-Dev] Question about BTree transaction data

2006-04-10 Thread Pascal Peregrina
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.
