RelStorage and ZEO aren't databases. At the database level, streaming
of blob data is supported by virtue of blobs being files. The storage
implementation is required to make them available as such.

BTW, my sense is that when blobs were first implemented, the
emphasis was on shared blob directories and the non-shared blob
implementation suffered from neglect, which I at least tried to
rectify in ZODB 3.9.
