Carsten Lohmann commented on KAFKA-12260: ----------------------------------------- It looks like this is fixed in Kafka client 3.0.0 and 3.1.0: https://github.com/apache/kafka/commit/e4f2f6f6e82cafbdea785d53521b96fe062e172d > PartitionsFor should not return null value > ------------------------------------------ > > Key: KAFKA-12260 > URL: https://issues.apache.org/jira/browse/KAFKA-12260 > Project: Kafka > Issue Type: Improvement > Components: consumer > Reporter: Boyang Chen > Assignee: Boyang Chen > Priority: Minor > > consumer.partitionsFor() could return null value when topic was not found. > This was not properly documented and was error-prone when the return type was > a list. We should fix the logic internally to prevent partitionsFor returning > null result. -- This message was sent by Atlassian Jira (v8.20.1#820001)
