咨询一个问题，按照事件时间10分钟watermark，，flink里用到了连续的两个窗口，第一个3分

咨询一个问题，按照事件时间10分钟watermark，，flink里用到了连续的两个窗口，第一个3分钟，第二个10分钟，然后我就发现第二个10分钟窗口里的数据，按照record本身的时间，是不应该在第二个窗口里的，请问record所在的窗口为什么没有按照本身的事件时间分配窗口？为什么3分钟窗口这一批数据作为一个整体，要么都在，要么都不在下游的10分钟窗口里

各位大佬我一直有个疑问概念: WaterMark可以理解为是为了解决窗口的触发时#Flink

各位大佬我一直有个疑问概念: WaterMark可以理解为是为了解决窗口的触发时机的问题问题: 如果没有窗口是不是没有WaterMark这个概念了 #Flink
