Kafka CreateTopics Response Wire Format v4 — Binary Protocol Layout

What is CreateTopics?

Provisions new topics via kafka-topics.sh --create or AdminClient.createTopics(). The validateOnly flag lets CI pipelines check if a topic config is valid without creating it; NOT_CONTROLLER errors mean the request hit a non-controller broker and will be auto-retried.
