Thanks Sendoh. Is there a way to advance watermark even when there are no incoming events. What exactly does setAutoWatermarkInterval do?
Also I don't see the watermark displayed in flink dashboard. Will the watermark advance only when there is data from all consuming kafka topic and partitions? I have 3 topics with 3 partitions in each topic. Thanks.
