" Indexed select statement consists of two queries - the view query used to extract base keys and the base query that uses those keys to return base rows. The main idea of this series is to replace raw proxy.query() call during the view query to one that uses a pager. Additionally, paging info from the view query needs to be returned to the client, in order to be used later for requesting new pages.
