Hi, reading through the documentation regarding waterrmarks, it is not clear to me if watermarks are also used by map/flatmpat operators or just by window operators.
My application reads from a kafka topic (with multiple partitions) and extracts assigns timestamp on each tuple based on some fields of the kafka records. A following keyBy operator creates partitions and sends the tuples to the corresponding downstream map/flatmap operator. I have set the timecharacteristic to EventTime. However, it seems that the flatmap operator *does not* guaranteed that it will process elements in an deterministic time order. Is this correct? Antonis
