[ZODB-Dev] Splitting a large ZODB file storage - any light-weight approach?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi there, we have some huge ZODB file storage (60-80 GB each) and we want to split the storage into a number of smaller storage (easier to handle for backup and packing). The storages themselves only contain a few (Zope 2) folders - let's say folders A, B, C - within the root and we want to create seperate storages for A, B, C. Is there some easier approach than using the Zope 2 CopyManager API for moving data around. The ZODB storage iterator API comes to my mind... is this a suitable approach or is there some other light-weight approach (compared to using CopyManager API)?

Which could generate a database with your exported content in it. So you could simply wire up the new storage in .conf file, delete the original and remount it with ZMI. ___ 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

You can take a loot into: http://svn.erp5.org/erp5/trunk/utils/zodb-cutter/ Seems a tool for what you want to do.
