Hello Fabian <
[hidden email]>
A small question: during the course of our recent conversation on the behaviour of window,trigger and evictor, you had mentioned that if I - the application programmer - do not attach a trigger to a window, Flink will attach one by itself. This trigger ensures that the size of the window never grows beyond a threshold, thereby ensuring that a burgeoning window never inflicts a OOM on Flink.
Is this a special Trigger? What's the name of the class? Moreover, how is that threshold size (of the window) determined? Is it configurable?
TIA.
