Waterstream is the first and the only MQTT platform on the market leveraging Apache Kafka as its own storage and distribution engine. Every incoming MQTT message is immediately available in your Microservices architecture or your analytics platform without any further processing. Vice-versa, every message written on a Kafka topic it’s sent to MQTT clients. All the necessary MQTT state, like subscriptions and QoS message status is also stored in Kafka—no need for additional storage.
