Heh, I am obviously not paying enough attention. Don't pack that database. :-) Shane ___ 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

It's a fair point. I can't think of anything, but given that Shane didn't make your point, I wonder if he can? cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk ___ 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

[ZODB-Dev] RelStorage recommended maintenance
Hi Shane, I'm wondering what the recommended maintenance for these two types of storage are that I use: - keep-history=true, never want to lose any revisions My guess is zodbpack with pack-gc as true, but what do I specify for the number of days in order to keep all history? - keep-history=false, never want any revisions or unreferenced objects My guess is zodbpack with pack-gc as true and days as 0? All storages will be in MySQL, are there any duty-cycle or other parameters I should tweak from their default values? How often do you recommend running zodbpack? cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk ___ 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
