             Summary: 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 [https://stackoverflow.com/q/46175275/952135 other users].

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.
