What timestamp field contains differs significantly depending on Kafka's `message.timestamp.type` configuration. The situation is even worse when a topic migrated into a new topic (because of transformation or something). 2. As I've seen users are dealing with problems which are making filtering based on event time but this field is most of the time processing time. This has to be mentioned. Some compacted limitations would be good add. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
