dengziming commented on KAFKA-10753:
------------------------------------
Every time you call KafkaConsumer.poll(), auto-commit is invoked repeatedly if
no records are returned before timeout, not only auto-commit is invoked,
heartbeat will also be invoked if `max.poll.interval.ms` is set to 0.
One suggestion is to add a backoff in `KafkaConsumer.pollForFetches`, or just
add docs to remind the user how to set timeout configs.
> check if ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG > 0
