Event-time windows without watermarkwarning

windowed-aggregation-without-watermark

Event-time windows need a watermark to know when a window is complete. Without one the processor either waits forever or closes windows early and silently drops late events.

— all of these hold:
— the node's `windowing` is "event-time"
— the node's `watermarkSeconds` has no value

Use it in a design
