-----------------------------------------------------------------------

Part 1 is referring to Kafka Streams configuration. The `max.poll.interval.ms` was over written to Integer.MAX_VALUE in Kafka Streams module. In Kafka 2.3.0, this config is reduced to it's default 300 secs (https://issues.apache.org/jira/browse/KAFKA-6399).

Part 2 is referring to the plain consumer group management where the default value is 300 secs.

> Dears,
> Two parts (referenced below) of [documentation |http://kafka.apache.org/documentation/] are not quite consistent.
> In one text we can read, that max.poll.interval.ms has defaut value Integer.MAX_VALUE, in the other it is 300 000.
> Part 1.
> {quote}
> The default values for two configurations of the StreamsConfig class were changed to improve the resiliency of Kafka Streams applications. The internal Kafka Streams producer retries default value was changed from 0 to 10. The internal Kafka Streams consumer max.poll.interval.ms default value was changed from 300000 to {color:#FF0000}Integer.MAX_VALUE{color}.

> Part 2. - Table
> |max.poll.interval.ms|The maximum delay between invocations of poll() when using consumer group management. This places an upper bound on the amount of time that the consumer can be idle before fetching more records. If poll() is not called before expiration of this timeout, then the consumer is considered failed and the group will rebalance in order to reassign the partitions to another member.|int|{color:#FF0000}300000{color}|[1,...]|medium|
> Which value is then default :-)
