Hi Till. Thank you for suggesting. We know the timestamp is correct because another Flink job is running with the three topics correctly. We also know the operators work well before window apply() because we check the result before window apply().
What currently I have a doubt is the necessary parallelisms for window operation if reprocessing a skew input from Kafka because it works with fewer events, and small topics always appear while big topics disappear.
