Time Window (时间窗口) 根据不同的业务场景,Time Window 也可以分为三种类型,分别是滚动窗口(Tumbling Window)、滑动窗口(Sliding Window)和会话窗口(Session Window) 滚动窗口(Tumbling Window) 滚动窗口是根据固定时间进行切分,且窗口和窗口之间的元素互不重叠。这种类型的窗口的最大特点是比较简单。只需要指定一个...

对于TimeWindow(根据时间划分窗口), 可以根据窗口实现原理的不同分成三类:滚动窗口(Tumbling Window)、滑动窗口(Sliding Window)和会话窗口(Session Window)。 滚动窗口(Tumbling Windows) 将数据依据固定的窗口长度对数据进行切片。 特点:时间对齐,窗口长度固定,没有重叠。

Use the sliding period as a unit to divide a window into different panes. A window consists of one or multiple panes. A pane is essentially a sliding period. For example, the sliding period (namely, the pane) ofwindow(SlidingEventTimeWindows.of(Time.seconds(20), Time.seconds.of(5)))las...
