Flink数据源长时间没有数据进来，窗口的触发器怎么触发执行？

Flink触发器定义了何时触发计算，但是reduce这种每来一个元素就计算？

Flink触发器定义了何时触发计算，但是reduce这种每来一个元素就计算。那是不是理解触发器和窗口函数有关系？但是文档说默认触发器和窗口分配器有关，似乎和窗口函数无关？

[Flink]Flink1.3 Stream指南五窗口触发器与驱逐器

1. 窗口触发器触发器(Trigger)确定窗口(由窗口分配器形成)何时准备好被窗口函数处理。每个窗口分配器都带有默认触发器。如果默认触发器不满足你的要求，可以使用trigger(...)指定自定义触发器。触发器接口有五种方法允许触发器对不同的事件做出反应： public abstract Tr...
