If MQTT Broker is clustered, why need kafka? 2.

​Hello, Thanks for reaching out on our HiveMQ Community Forum. Please review our documentation on Kafka [here](https://docs.hivemq.com/hivemq-kafka-extension/latest/index.html), which explains more about its role when integrated with HiveMQ. The diagram provided here is simply to convey HiveMQs capability to scale across multiple company facilities/factories as one MQTT ecosystem. ​I hope this helps. Regards, Gil
