Zodbanalyze is useful to see what is going on inside storage and gather some statistics about objects and their sizes. However until now it was working only with Filestorage. The first patch teaches zodbanalyze to work with arbitrary ZODB storage.
Then the second patch teaches zodbanalyze to accept a history range to analyze - instead of analyzing whole storage. This should be practical to see what is going on in recent times, e.g. in last week or last day.
This should hopefully make it a bit more clear to understand if we see unexpected database growth.
