> If you try to create a topic and the replication factor cannot be satisfied, Kafka will return `INVALID_REPLICATION_FACTOR`. If the topic already exists, we should probably return `TOPIC_ALREADY_EXISTS` instead. You won't see this problem if using TopicCommand because we check existence prior to creating the topic.
