Re: bits-service fog usage question

I can't comment on the common use cases, and who this change would break.
However, I'm very much in favor of hiding this implementation detail from
our API. Letting a library's internal API leak into our product surface
area is a very bad thing for us long term

Subject: [cf-dev] bits-service fog usage question
------------------------------



Hi everybody,

we are beginning work on the Bits Service proposed here [1] for handling
all kinds of blobstore related operations - a functionality that is in the
cloud controller today. Cloud controller currently uses the ruby gem 'fog'
[2] for interactions with the back-end blobstore.
We are thinking about removing the dependency on the ruby fog gem and
would like to better understand what blobstores and configurations you, in
the community, are using today. Unfortunately, the fact that this gem is
used leaks out to the cc configuration [3] by taking an opaque fog hash,
and therefore it could potentially be used in many ways.

We would like to get feedback on whether it would be fine if the new bits
service only supported s3 compatible blobstores, externally provided nfs,
and webdav (and no longer everything that fog potentially supports).
Would you be impacted by such a decision, and how?
What connection parameters/features of fog do you currently make use of?
