MuleSoft Kafka Integration: How to Publish and Consume Kafka Messages Using Mule 4
In order to integrate your Mule Application with Kafka, you need to first add Kafka Module (Kafka Connector) by signing in to Exchange. Once you have added Kafka Module in your Mule 4 Project, you will see various operations available in Kafka Module including operations to send messages to Kafka topics and consuming messages from Kafka Topics.
In order to connect with Kafka, you need to ensure that Kafka server is running. I already explained in another tutorial, how to install and setup Kafka on Windows Machine and how to run Kafka Broker and Kafka Zookeeper as windows services.
Refer to below video tutorial about Mule 4 Kafka Integration and by following all the steps in this tutorial, you will learn Kafka MuleSoft Integration in detail.
