desired behavior.
Also, I misspoke earlier. It's not just the logging. They want to separate the

Kafka logs traffic to the Controller node separately from the normal
traffic to the node. In order to differentiate it subtracts the broker id
from 2147483647 (max int) and uses the result as the "node id" for the
controller.

Here is related code:
log.debug("Using older server API v{} to send {} {} with
correlation id {} to node {}",
header.apiVersion(), clientRequest.apiKey(),
request, clientRequest.correlationId(), nodeId);
2147483647 is the node Id.
