Class Summary

Class	Description
HeapPriorityQueue<T extends HeapPriorityQueue.HeapPriorityQueueElement>	This class has similar functions with HeapPriorityQueue.
StatusWatermarkValve	A StatusWatermarkValve embodies the logic of how Watermark and WatermarkStatus are propagated to downstream outputs, given a set of one or multiple subpartitions that continuously receive them.
StatusWatermarkValve.SubpartitionStatus	An SubpartitionStatus keeps track of a subpartition's last watermark, stream status, and whether or not the subpartition's current watermark is aligned with the overall watermark output from the valve.
WatermarkStatus	A Watermark Status element informs stream tasks whether or not they should continue to expect watermarks from the input stream that sent them.
