This problem is as old as data processing. The "page N of M" situation
which requires that the entire data set be read to get M. Once you have
read the entire set you have many options on how you handle your window
on that dataset. You could use local storage for it all or take
advantage of

You can’t ask Google for more than the first 1,000 hits on any

Web based systems require paging that does not iterate through all records.
What is required is a means to LIMIT the results read from the database but
at the same time know how many records WOULD have been returned if the query

I second this. I don't mind having to post or refresh my subscription every
once in a while. It would however be important for me to receive a notification
to refresh my subscription instead of just silently removing my subscription.
