 By using the link:{kafkaapi}/org/apache/kafka/clients/producer/KafkaProducer.html[KafkaProducer] API directly you open up even more options if you require transactions (exactly-once delivery) or want control over when records are flushed etc.

+The previous section introduced the ability to use a Kafka docker container. This is possible by using 
+https://micronaut-projects.github.io/micronaut-test-resources/latest/guide/[Micronaut Test Resources].
+
+The recommended approach to get started is to use https://micronaut.io/launch[Micronaut Launch] and select the `test-resources` feature.
+
+Micronaut Test Resources will automatically start a Kafka container and provide the value of the `kafka.bootstrap.servers` property.
+
+TIP: For more information, see the https://micronaut-projects.github.io/micronaut-test-resources/snapshot/guide/#modules-kafka[Kafka section of the Test Resources documentation].
