[openstack-dev] Offset support in REST API pagination

First, here is some background on this topic:

Does anyone have any insight as to why offset is not supported in the REST
API calls that support pagination?   I realize that there are tradeoffs
when using a offset (vs. marker) but I believe that there is value in
supporting both.  For example, if you want to jump to the n-th page of data
without having to traverse all of the previous pages.

Is there a reason why the APIs do not support either a marker or an offset
(obviously not both) on the API request?  It appears that sqlalchemy has
offset support.

Also, it seems that cinder at least looks for the offset parameter (but
ignores it).  Does this mean that it was supported at one time but later
the support was removed?

Thanks for the information.
