--------------------------------------------------------------

> I am not sure how would the reference.key be retrieved from the Backend
[~amjain] I guess no need. FDS assumes reference.key lying in $\{path]}.  you can copy FDS implementation in CachingFDS.

>Would you be able to provide a patch for this.
no b/w ATM :(

> FDS on SAN/NAS storage is not efficient as it involves network call. In OAK. indexes are stored SAN/NAS and even idle system does lot of read system generated data. 
> Enable caching in FDS so the reads are done locally and async upload to SAN/NAS
