(without requiring you to manually implement an acknowledgment protocol). However, the request-response approach may not always be the best fit. For example, streaming transporters, such asKafkaorNATS streaming,

For example, in the case of NATS with wildcard subscriptions, you may want to get the original subject that the producer has sent the message to. Likewise, in Kafka you may want to access the message headers. In order to accomplish that, you can use built-in decorators as follows:...
