Asynchronous Request-Reply
Decouple back-end processing from a front-end host
Intent & Description
The Asynchronous Request-Reply pattern decouples back-end processing from a front-end host. This pattern is useful when back-end processing must be asynchronous, but the front end requires a clear and timely response. The front end initiates a request and receives a response acknowledging receipt, while actual processing happens asynchronously.
Real-world Use Case
Use when back-end processing takes time but the front end needs immediate response acknowledgment.
