Purpose

The HiveMQ Enterprise Extension for Kafka adds monitored, bi-directional MQTT messaging to and from your Kafka installation. 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 (and vice versa) in a high-performant, scalable and reliable manner.

• 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.
• Poll information from a Kafka topic and publish this information as MQTT messages to one or more MQTT topics.
• Use multiple MQTT topic filters with full support of MQTT wildcards to route MQTT messages to the desired Kafka topic.
• End-to-end persistent messaging guarantees from device to Kafka so no messages are lost.
• Track all of the MQTT messages to and from Kafka on a centralized HiveMQ control center.

Evaluation License

HiveMQ Enterprise Extension for Kafka is available for free download and evaluation. This extension only works with HiveMQ Professional or HiveMQ Enterprise.

The evaluation version is limited to operate for only 5 hours. You will need to restart HiveMQ each time you want to reset the 5 hour limit. Please contact HiveMQ sales if you would like a longer evaluation license.
