If that would work it should still be easier on memory usage.
No. Although some documentation I've seen talks about "streaming" blobs from the database, neither RelStorage nor ZEO actually streams blobs. Blobs have to be fully downloaded to the filesystem before application code can see them. Without a cache directory, the files would have no reasonable place to go. OTOH, there are a lot of Plone 3 instances out there and converting them to Plone 4 is going to be a lot of work. As an interim step, maybe we should figure out what it would take to Plone 3 work with ZODB 3.9 or 3.10. Perhaps the incompatibility is shallow.
