Abstract
Systems and methods maintain a toplist associated with a sliding window having m elements. The toplist can include the top k elements of the sliding window, where k is less than m (typically an order of magnitude or more less than m). As new elements are received from a data stream, a counter associated with the new element is updated and the new element is inserted into the sliding window. If the toplist has less than k elements, the new element is added. Otherwise, if the new element is already in the toplist, its counter value is updated with the new value. Otherwise, if the new element's counter is smaller than the smallest element in toplist, then do nothing. If the new element counter is larger than the smallest counter in the toplist, the smallest element is discarded from the toplist and the new element is inserted.
