[ZODB-Dev] ZODB load/save tracing

[Christian Theune]

Hi,

I'm pretty sure there are no hooks around that do what you need.

The methods you want to tap into would be

store()
load*()

on the storages.

You might want to look into how the BlobStorage was created to make
yourself a "tracing storage" that can be wrapped around an existing
storage to allow usage with multiple other storages.

This could be a useful extensions to ZODB. If you go this way,  I'd be
happy to help out with some of the packaging mechanics and getting the
ZConfig parts fletched out.

Christian
