MQTT¶
About
MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT).
It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth.
MQTT today is used in a wide variety of industries, such as automotive, manufacturing, telecommunications, and oil and gas. It enables efficient, reliable messaging between devices and backends over constrained networks.
Through CrateDB’s MQTT integration you can use any MQTT broker such as Coreflux, Eclipse Mosquitto, EMQX, HiveMQ, VerneMQ, or RabbitMQ. Azure IoT Hub speaks MQTT as well, but with protocol and authentication specifics; please adjust settings accordingly.
