Pagination is a technique for breaking large record sets into smaller portions called pages.

He uses results from the Twitter and Facebook APIs in his examples, grabbing tweets matching the search term "php". He briefly explains some of the issues with real-time pagination and how it compares with standard pagination techniques. He uses the "after" and "before" functionality of each API to only pull the data needed, not the entire list of latest posts. This is added to a list in order and shown when the user view is refreshed. He includes the code for implementing the cursor-based handling and how to echo the results back out to a view.
