Paging without loading all data from the backend first about bforms HOT 2 OPEN

We are using the BsGrid for data-sets with millions of rows, the BsBaseGridRepository doesn't require for all the records to be loaded in memory. We use take/skip that does a count on all records and no offset that doesn't need to run count and is optimized for large data-sets. In both cases we never load all records.

Good to know that it works..

I guess my confusion stems from the fact that all those queries, the take/skip and the mapping all base on this.Query.. which is an IQueryable. If I had direct access to the database, I guess that would work. I've "inherited" a project though where the data is on a REST backend. And that way, there's no IQueryable to make queries on. While the backend supports paging itself and not only returns records, but also the total number of records for any query, I then wonder how to map that. The communication to the backend is also async (you know how invasive that is) which further complicates matters.

So, what would you recommend in that case? Build an IQueryable abstraction for the remote system? And if so.. do I need the whole shebang or can I get away with implementing only parts of it?
