When you configure a Kafka target service, specify the topic on which it sends messages and the IP address and port on which the Kafka broker runs.
If you deploy a data flow that contains a Kafta target service, you might have duplication of messages when the EDS Node fails and restarts. The Kafka target service that is running on that EDS Node might receive duplicate messages from the source service when the node comes up later. This duplication of messages occurs because the source service does not receive an acknowledgment from the Kafka target service and resends the messages.
In a high availability setup, you might have duplication of messages when a EDS Node process fails over to one of the backup machines.
