--------------------------------------
Summary: Improve expired poll interval logging by showing exceeded
time
Key: KAFKA-16695
URL: https://issues.apache.org/jira/browse/KAFKA-16695
Project: Kafka
Issue Type: Task
Components: clients, consumer
Reporter: Lianet Magrans
Assignee: Lianet Magrans
When a consumer poll iteration takes longer than the max.poll.interval, the
consumer logs a warn suggesting that the max.poll.interval config was exceeded,
and pro-actively leaves the group. The log suggests to consider adjusting the
max.poll.interval.config which should help in the cases of long processing
times. We should consider adding the info of how much time the interval was
exceeded, since it could be helpful in guiding the user to effectively adjust
the config. This is done in other clients, that log this kind of messages in
this situation:
{quote}Application maximum poll interval (300000ms) exceeded by 255ms (adjust
max.poll.interval.ms for long-running message processing): leaving group{quote}
