Thanks, I've finally backported some fixes for StorageAdapter, which
was overwriting too many fields during a document update.
Wow, I remember those fixes, one of the last generic work on CPS I've
done as a Nuxeo employee,
The primary goal was to avoid useless writes in LDAP backing
directories, while still being able to update a meta directory upstairs
(for CPS specific fields that would be stored in another - ZODB - backing).
Did you backport this on your project for directories or documents ?
I've always wondered what the overall (positive, I hope) performance
impact in the case of documents would be, and never had a chance to
measure that. Any numbers to share ?
I've backported it for CPSDocuments, to avoid dataloss with DiskFile objects
overwriting an already published file. This is not related to performance so I
didn't measure anything.
Cheers,
