Artur updated KAFKA-9739: ------------------------- Attachment: topology-definition-fragment.java > StreamsBuilder.build fails with StreamsException "Found a null > keyChangingChild node for OptimizableRepartitionNode" > -------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-9739 > URL: https://issues.apache.org/jira/browse/KAFKA-9739 > Project: Kafka > Issue Type: Bug > Components: streams > Affects Versions: 2.4.1 > Reporter: Artur > Assignee: Bill Bejeck > Priority: Major > Attachments: streams-exception-log.txt, > topology-definition-fragment.java, topology-description.txt > > > We created a topology using Streams DSL (topology description is available in > the attached topology-description.txt, no optimization). > Topology works fine with {{topology.optimization=none}}, however it fails to > build with StreamsException "Found a null keyChangingChild node for > OptimizableRepartitionNode" if we set {{topology.optimization=all}} > (exception stack trace is attached streams-exception-log.txt). > We used [https://zz85.github.io/kafka-streams-viz/] to visualize topology and > try to guess what might be upsetting optimizer, yet did not manage to figure > it out ourselves. -- This message was sent by Atlassian Jira (v8.3.4#803005)
