A Function must return an HTTP response immediately but continue processing asynchronously. Which Durable Functions pattern implements this?
- A Monitor pattern
- B Async HTTP API (202 Accepted + status polling endpoint) (correct answer)
- C Function chaining
- D Fan-out/fan-in
Shortcut: The Async HTTP API pattern starts an orchestration and immediately returns 202 Accepted with a status URL. The client polls the status endpoint until the orchestration completes.
