The Akubra Project is a new effort to provide a pluggable file storage interface that can be adapted to almost any storage subsystem. Akubra supports both ordinary and transactional storage systems, but makes simplifying assumptions in order to achieve a high level of interoperability between storage systems:
- a Blob is a finite-length bitstream with an id (a URI)
- a Blob Store is primarily concerned with providing read/write access to blobs.
