Hi Till, Yes, I understand that. I am just asking why. If I am assigning the timestamps. why can’t flink deal with the window based on the event time? i.e TumblingEventTimeWindows. Why should I set the whole env to be ticking on event time?
It is just that I have some windows that needs to be processing time, and others needs to be event time.

Otherwise the event time windows won’t work.

I would like Flink to be ticking on processing time, but also utilize the TumblingEventTimeWindows which is based on event time. It is not possible because of : java.lang.RuntimeException: Record has Long.MIN_VALUE timestamp (= no timestamp marker).
