> A filesystem is the canonical means for storing files - just use it Sure but what about the many use cases where you're not really storing files but metadata or other generated data? A simple example might be photo libraries. The photos themselves are files but are the 5kB small and 50kB medium thumbnails generated from the photos worth storing as files? Or should they be stored as blobs in the database along with their other metadata? It's good to know where the cutoff should be.
