Listener Notifications
The following sections provide instructions for configuring and managing Adapter for Apache Kafka listener notifications. When a listener receives a message from a Kafka topic, then it passes the message to an enabled listener notification that is associated with the listener.
Important:
The message is lost if you do not configure any notifications with a listener, or if you do not enable any notifications which are already configured. Software AG recommends that you enable a listener notification before you enable the listener.
Ideally, you must configure only one notification per listener. If you configure multiple listener notifications with the same listener, the listener passes the data to the listener notifications created first. You can view and edit the order in which the listener notifications receive the data from the listener. For more information, see
Editing the Notification Order of a
Listener and
Viewing the Notification Order of a
Listener. If you have configured multiple notifications with a listener,
Software AG recommends that you enable only the notification that needs to be executed.
Adapter for Apache Kafka provides following types of listener notifications that you can configure:
Synchronous Apache Kafka Listener Notifications
Asynchronous Apache Kafka Listener Notifications
Synchronous Confluent Kafka Listener Notifications
Asynchronous Confluent Kafka Listener Notifications
