Question:
When resetting Kafka origin, the following error is displayed: "Origin 'Kafka Consumer' doesn't support reset operation". How come the reset operation is not supported?
Answer:
You cannot reset the origin for Kafka origins as the offsets for a consumer group are stored in Kafka ('__consumer_offsets' topic). Resetting must be done on the Kafka brokers with the relevant command/API. If your goal is simply to start from a new 'auto.offset.reset' value and don't care about re-using the pre-existing consumer group, then you can just specify a new consumer group in the Kafka origin configuration and restart the pipeline.
