ZODB doesn't provide any direct support because it has no notion of tree. In Zope 2, you could export the folder and look at the size of the export.

Sadly, when you're trying to figure out which folder is using all the space on a disk that's running out of space, that's not practical...

How about simply writing a script that crawls the ZODB and gives you paths and sizes? jens _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@... https://mail.zope.org/mailman/listinfo/zodb-dev smime.p7s (6K) Download Attachment

Indeed, and what's the magic incantation to get the size of the object as it is on disk? 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@... https://mail.zope.org/mailman/listinfo/zodb-dev

Perhaps useful: https://bugs.launchpad.net/zodb/+bug/424172 (but pretty low-level). Andreas `[lists.vcf]` `begin:vcard fn:Andreas Jung n:Jung;Andreas org:ZOPYX Ltd. & Co.

There is none that I know. I would simply look at the data items I know from the object in the ZODB. Like, I know how OFS.Image and OFS.File save their data and can determine the size that way. You would have to have knowledge about each type of object encountered. jens _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@... https://mail.zope.org/mailman/listinfo/zodb-dev smime.p7s (6K) Download Attachment

Aside from life, the universe, and everything... Database record header. There's also space for transaction meta data, but that's amorized over an unknown number of records.
