John Roesler created KAFKA-9562: ----------------------------------- Summary: Streams not making progress under heavy failures with EOS enabled on 2.5 branch Key: KAFKA-9562 URL: https://issues.apache.org/jira/browse/KAFKA-9562 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 2.5.0 Reporter: John Roesler Assignee: Boyang Chen Fix For: 2.5.0
During soak testing in preparation for the 2.5.0 release, we have discovered a case in which Streams appears to stop making progress. Specifically, this is a failure-resilience test in which we inject network faults separating the instances from the brokers roughly every twenty minutes. On 2.4, Streams would obviously spend a lot of time rebalancing under this scenario, but would still make progress. However, on the current 2.5 branch, Streams effectively stops making progress except rarely. This appears to be a severe regression, so I'm filing this ticket as a 2.5.0 release blocker. -- This message was sent by Atlassian Jira (v8.3.4#803005)
