Description

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:

Application maximum poll interval (300000ms) exceeded by 255ms (adjust max.poll.interval.ms for long-running message processing): leaving group
