Detailed Description

Key/value blob storage for a particular storage medium type (e.g.

RDBMs, files)

There can be multiple "locations" for a storage medium type (e.g. DB clusters, filesystems). Blobs are stored under URLs of the form "<protocol>://<location>/<path>". Each type of storage medium has an associated protocol.
