------------------------------------
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.
