Viliam Durina resolved KAFKA-5881.
----------------------------------
Resolution: Not A Problem
I can confirm the behaviour, after setting "metadata.max.age.ms" to zero I get
fresh copy of metadata each time, including new partitions.
> Consuming from added partitions without restarting the consumer
> ---------------------------------------------------------------
>
> Key: KAFKA-5881
> URL: https://issues.apache.org/jira/browse/KAFKA-5881
> Project: Kafka
> Issue Type: Improvement
> Components: consumer
> Affects Versions: 0.11.0.0
> Reporter: Viliam Durina
>
> Currently the {{KafkaConsumer}} is not able to return events from newly added
> partitions, neither in automatic nor in manual assignment. I have to create a
> new consumer. This was a surprise to me and [other
> users|https://stackoverflow.com/q/46175275/952135].
> With manual assignment, the {{consumer.partitionsFor("topic")}} should
> eventually return new partitions.
> With automatic assignment, one of the consumers should start consuming from
> new partitions.
> If this is technically not possible, it should at least be documented.
