Description

Context

Old blueprint: http://tracker.ceph.com/projects/ceph/wiki/Osd_-_tiering_-_object_redirects

Discussed on CDM_06-APR-2016 (http://tracker.ceph.com/projects/ceph/wiki/CDM_06-APR-2016). Building block for deduplication.

Related: Feature #15433 (CAS Pools)

Idea

Add symlink-like feature: Objects may point to a location instead of storing data. Clients can resolve this redirection using additional metadata, which may be as simple as another pool/object name, URL or a byte range + fingerprint mapping for deduplication.
