Purpose

The HiveMQ Enterprise Extension for Kafka makes it possible to seamlessly integrate MQTT messages with Kafka clusters. The extension implements the native Kafka protocol so HiveMQ acts as a first-class Kafka client. This allows for MQTT topics to be mapped directly to Kafka topics and forward messages directly to multiple Kafka clusters in a high-performant, scalable and reliable manner.

HiveMQ Enterprise Extension for Kafka includes the following capabilities:

• Connect and route IoT device data to multiple Kafka clusters allowing for a single HiveMQ platform to support different types of devices and routing device data to different back-end applications.
• Support of all MQTT 3.1.1 and MQTT 5 features.
• Makes it possible to map millions of MQTT topics to a limited number of Kafka topics using MQTT wildcards.
• End-to-end persistent messaging guarantees from device to Kafka so no messages are lost.
• Monitoring of MQTT messages written to Kafka through the HiveMQ Control Center.
