ОШИБКА потребителя консоли Kafka «Ошибка фиксации смещения в разделе»

Я использую kafka-console-consumer для исследования темы кафки.

Время от времени я получаю это сообщение об ошибке, за которым следуют 2 предупреждения:

[2018-05-01 18:14:38,888] ERROR [Consumer clientId=consumer-1, groupId=console-consumer-56648] Offset commit failed on partition my-topic-0 at offset 444: The coordinator is not aware of this member. (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)

[2018-05-01 18:14:38,888] WARN [Consumer clientId=consumer-1, groupId=console-consumer-56648] Asynchronous auto-commit of offsets {my-topic-0=OffsetAndMetadata{offset=444, metadata=''}} failed: Commit cannot be completed since the group has already rebalanced and assigned the partitions to another member. This means that the time between subsequent calls to poll() was longer than the configured max.poll.interval.ms, which typically implies that the poll loop is spending too much time message processing. You can address this either by increasing the session timeout or by reducing the maximum size of batches returned in poll() with max.poll.records. (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)

В журналах предупреждений указано, что:

Итак, мне нужно либо увеличить max.poll.interval.ms, либо уменьшить max.poll.records.

Посоветуйте, пожалуйста, каковы будут последствия каждого метода и какой из них предпочтительнее в разных ситуациях?
