Hi, Ken
We haven't started any work on the File store yet, it's a bit down our
list. The first store is DB, followed by a lua intermediate layer. If
someone else wanted to work on a File store earlier, I'd be happy to
give pointers.
My tentative plan for File store was to use POSIX as the API. This
would allow us to work on any local filesystem, and likely on many
locally-mounted remote filesystems as well.

Daniel, do you have any idea in mind about how it will be implemented?
For example, what kind of file interface (e.g. POSIX, NFS) will RGW use to access the backend?
I am interested in File backend because it might be useful if RGW could be backed by File backend such as NFS server instead of RADOS.
I guess RADOS does not work well on some storage devices such as tape, but such devices can alternatively be accessed via file interface.
In such a case, it might be useful if RGW could access the File backend and treat it as a different storage class from STANDARD.
Sincerely,
Ken Iizawa
