Node-Red module for Apache Kafka publish/subscribe using the Confluent REST Proxy
Works with Apache Kafka 0.9 and 0.10 including Confluent Open Source and Confluent Enterprise distributions (versions 2.0 and 3.0).
Run the following command in the root directory of your Node-RED install
npm install node-red-contrib-confluent
Start node-red as normal or use the -v flag for more verbose debugging
Point your browser to http://localhost:1880
You should see orange confluent input and output nodes in the pallet on the left side of the screen.
Drag either confluent node to the canvas and double click to configure the topic, key, partition, rest-proxy, clientID and groupID.
Click on the pencil icon to the right of the rest-proxy selection box to configure a rest-proxy URL if one does not already exist.
Publish and subscribe just as you would with the mqtt node with some small differences namely:
- topics should not contain "/" or "." characters
- kafka wildcard/regex subscriptions are not yet fully tested
- ensure you have unique Group IDs configured unless you want multiple consumers to be in a Kafka consumer group
