Explanation: This configuration controls whether the topic is automatically created when subscribing to a non-existent topic. A topic will be auto-created only if this configuration is set to true and auto-topic creation is enabled on the broker using auto.create.topics.enable; otherwise auto-topic creation is not permitted.

Default Value: TRUE
Priority: MEDIUM
