Apache Kafka is a publish-subscribe messaging system. Kafka runs as a cluster comprised of one or more servers each of which is called a broker. Kafka brokers process data in the form of messages, publishes the messages to a topic, subscribes the messages from a topic, and then writes it to the Kafka target.
You can use the Kafka data object write operation as a target. If you want to configure high availability for the mapping, ensure that the Kafka cluster is highly available.
