Newstore is designed to put large objects and updates in the
filesystem, but to store small objects and overwrites inside of
RocksDB for faster access. You seem to have discovered that from the
other end, but I'd recommend looking at some of the Newstore design
discussions (and documents? I think there are emails and documents) if
you're going to be working with it.
