I use MQTT daily. I'm not sure why the commenter suggested it; it is orthogonal to queueing or log streams. MQTT is a publish/subscribe protocol for large scale distributed messaging, often used in small embedded devices or factories. It is made for efficient transfer of small, often byte sized payloads of IoT device data. It does not replace Kafka or RabbitMQ - messages should be read off of the MQTT broker as quickly as possible. ( I know this from experience - MQTT brokers get bogged down rapidly if there are too many messages "in flight") A very common pattern is to use MQTT for communications, and then Kafka or RabbitMq for large scale queuing of those messages for downstream applications.
