You can use the Apache Kafka Producer adapter to write a message to a Kafka topic.

Write a Message

Using the produce operation of the Apache Kafka adapter, you can write a message to a Kafka topic.

producerRecord is a complex structure that defines the message and target.The topic you want to write the message to is the only mandatory parameter.

The Kafka Producer returns some meta data about the processing of the message.

Transaction Handling

The xUML Runtime handles Apache Kafka Producer calls like is specified in the Runtime transaction concept. All producer calls within a session are wrapped into a dedicated transaction with a random unique transaction ID. These transactions can be rolled back until they have been committed.
You cannot set a custom transaction ID (transactional.id), therefore there will be no fencing.
