showuon opened a new pull request #10172: URL: https://github.com/apache/kafka/pull/10172
We now have the debug log [here](https://github.com/apache/kafka/blob/ea8ae976504e7a3f5c6f4a7efa5069d03316b093/clients/src/main/java/org/apache/kafka/clients/consumer/internals/ConsumerCoordinator.java#L587): ```java log.debug("Performing assignment using strategy {} with subscriptions {}", assignor.name(), subscriptions); ``` But we didn't override the toString method for subscription class, so user will get the useless debug info: ``` Performing assignment using strategy cooperative-sticky with subscriptions {consumer-groupId-1-7fd39d50-5dc1-46f0-860e-f0361eb2afc0=org.apache.kafka.clients.consumer.ConsumerPartitionAssignor$Subscription@247d8ae, consumer-groupId-1-09ffd69e-ce6c-4212-9d2c-218d60ad8d19=org.apache.kafka.clients.consumer.ConsumerPartitionAssignor$Subscription@48974e45} ``` ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
