Adapter for Apache Kafka listener continually monitors a Kafka topic for messages. When a message appears on a topic, the listener fetches the message based on the filter criteria that you select when you configure the listener. The listener passes the message to the listener notification. Unlike the Produce Service and Consume Service, you never invoke a listener directly from a service or client. Instead, a listener is a real-time process that you configure, enable, and disable using the Integration Server Administrator.
