Please, look into your use cases and keep asking "why", why do I need Kafka? Kafka is a beast of a tool. Example, I have seen people using Kafka after an MQTT broker, because... Kafka has an MQTT connector. Well, MQTT is a pub/sub architecture, so you are putting a pub/sub (Kafka) after another pub/sub MQTT, you need to be aware of that and need to think it thru if it makes sense for your use cases.
