Stanislav Kozlovski commented on KAFKA-7851: -------------------------------------------- [~cri] it's also worth mentioning that we have a KIP under way which implements part of that proposal for the Connect framework - https://cwiki.apache.org/confluence/display/KAFKA/KIP-415%3A+Incremental+Cooperative+Rebalancing+in+Kafka+Connect > 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 > Priority: Major > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
