Pluggable On-Disk Back-end APIs

The internal REST API used between the proxy server and the account, container and object server is almost identical to public Swift REST API, but with a few internal extensions (for example, update an account with a new container).

The pluggable back-end APIs for the three REST API servers (account, container, object) abstracts the needs for servicing the various REST APIs from the details of how data is laid out and stored on-disk.

The APIs are documented in the reference implementations for all three servers. For historical reasons, the object server backend reference implementation module is named diskfile, while the account and container server backend reference implementation modules are named appropriately.

This API is still under development and not yet finalized.
