Hello everyone, We need to move a considerable number of persistent objects (~40K) from one module to another, and we were wondering what is the best strategy to follow.
Our database contains around 90M objects, which is a pain to run `zodbupdate` on. So far these are the options that we thought of: * Running `zodbupdate`, possibly restricting the target object set to the places where we know that references to the class in question exist (otherwise it takes REALLY long); * Using the `classFactory`/`find_global` hook and basically converting the objects/refs to the new class as they are requested; The first one seems cleaner and less prone to problems in the future, but it will take ages (our current benchmarks point towards >1 day, although we could try to reduce that by limiting the search scope). The second one seems much easier to execute, but the fact that objects/references to the old and new classes will co-exist kind of bothers me. Has anyone ever done anything like this? Which approach have you followed? Any suggestions? Thanks a lot in advance, Cheers, Pedro P.S.: I am sending this from my private mail because this list seems to have been blacklisted in some servers, including my organization's. -- Pedro Ferreira http://pferreir.github.com _______________________________________________ For more information about ZODB, see http://zodb.org/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
