Yeah I looked at `DynamicConfigPublisher`. I think when I get the `ConfigRecord`, I need to check that its `resourceType` is for `BROKER` and only put those configs in `dynamicBrokerConfigs`. Then whether or not we update cluster defaults/per-broker is based on if `resourceName` is empty or contains the broker's id. -- This is an automated message from the Apache Git Service.
