NATS: integration and Request-Reply pattern #278
Description
https://docs.nats.io/nats-concepts/core-nats/reqreply
Request-Reply is a common pattern in modern distributed systems. A request is sent, and the application either waits on the response with a certain timeout, or receives a response asynchronously.
NATS supports the Request-Reply pattern using its core communication mechanism — publish and subscribe. A request is published on a given subject using a reply subject. Responders listen on that subject and send responses to the reply subject. Reply subjects are called "inbox". These are unique subjects that are dynamically directed back to the requester, regardless of the location of either party.
