Distributed Streams Algorithms for Sliding Windows [PDF]
'Massive data sets often arise as physically distributed, parallel data streams, and it is important to estimate various aggregates and statistics on the union of these streams. This paper presents algorithms for estimating aggregate
functions over a “sliding window” of the N most recent data items in one or more streams. [...] Our results are obtained using a novel family of synopsis data structures called waves.'
