Request-Reply Pattern

Simulate a request-reply pattern. Create a processRequest() function that takes a String request and returns Mono<String> with "Reply to: <request>". Send requests "ping", "hello", "status" and print each reply.

Request-Reply Pattern

Request-Reply over messaging simulates synchronous-like communication.

Why this works

The request-reply pattern maps each request to a response using flatMap. Each request is processed asynchronously, returning a Mono with the reply. This models how Kafka can be used for synchronous-like request/response flows.

Expected output

Reply to: ping
Reply to: hello
Reply to: status
