Re: Frequent appearance of "Marking the coordinator dead" message in consumer log

Someone, please help me. Only 1 or 2 out of 7 consumer groups keep rebalancing every 5-10mins. One topic is constantly receiving 10-20 msg/sec. The other one receives a bulk load after many hours of inactivity. CGs for both these topics are different. So, I see no observable pattern here. On Wed,

Shantanu, Sounds like your consumers are processing too many records between poll()s. Notice that max.poll.records is 50. If your consumer is taking up to 200ms to process each record, then you'd see up to 10 seconds between poll()s. If a consumer doesn't call poll() frequently enough, Kafka will

Hi Ryanne, Thanks for your response. I had even tried with 5 records and session timeout as big as 10 minutes. Logs still showed that consumer group rebalanced many times. Also there is another mystery, some CGs take upto 10 minutes to subscribe to topic and start consumption. Why might that be ha
