I doubt it. Thousnads of people are doing this and do not report the same behavior. What is more likely is that a programmer is changing a persistent object very often. One of the downsides of the ZODB is that it is so transparent it is possible to unwillingly make database changes. A design pattern for RDBMS is to have 2 pools. READ pool and WRITE pool. Often the READ pool comes from some replica and WRITE is to the master. I'm unsure this pattern would work for ZODB. I know Malthe was thinking about this but unsure if he had anything concrete. cheers alan _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
