Hi all, I would like to propose KIP-1297: Role-Aware Metric Tags for NodeToControllerChannelManagerImpl.
This KIP proposes making the metric tag used by Selector metrics in NodeToControllerChannelManagerImpl role-aware: - controller-only nodes use NodeId - broker-only and combined-role nodes continue using BrokerId The motivation is that BrokerId is misleading for controller-only nodes in KRaft mode, while preserving current broker metrics avoids unnecessary compatibility impact. KIP page: https://cwiki.apache.org/confluence/display/KAFKA/KIP-1297%3A+Role-Aware+Metric+Tags+for+NodeToControllerChannelManagerImpl JIRA: https://issues.apache.org/jira/browse/KAFKA-20199 Feedback is welcome. Thanks, Nilesh
