Downstream Change Summary Please see the scope doc and let Query know if any questions Description of Linked TicketEpic Summary SummaryAdd a $top accumulator that returns an array of expressions evaluated for top n documents according to a given sort order MotivationOne common analytical task is to find the top or bottom n elements in each cohort. For example, we are interested in the 10 best salespeople for each region based on their individual sales, or in the 5 slowest queries issued by a given tenant on each day. This is a generalization of finding the best or worst element. Cast of Characters
