[jira] [Created] (KAFKA-7851) Continue data streaming while rebalancing

Christian Richter created KAFKA-7851:
----------------------------------------

             Summary: Continue data streaming while rebalancing
                 Key: KAFKA-7851
                 URL: https://issues.apache.org/jira/browse/KAFKA-7851
             Project: Kafka
          Issue Type: Improvement
            Reporter: Christian Richter


At the moment, consumers will not receive further data when a rebalancing is triggered. In cases where many hundreds of consumers are re-balanced, the data stream is significantly interrupted by the rebalancing, especially as the time for the rebalancing is longer for many consumers.

By still streaming data to the consumers till the new generation is put in place, the data stream would be more consistent and stable.
