Hey Shaohan, Thanks for your reply, much appreciated. We are using Kafka 2.4.1. Although we use the Confluent platform under Confluent Licence, I don't think this matters.
We are using compression.type=GZIP for all our producers. We create all topics with compression.type=GZIP i.e. per topic level. When I do a "describe" of a kafka topic, I see metadata confirming that it's enabled for GZIP compressed data. That's all I could say.
