A Durable Function implements a human approval workflow that may wait days for a response. Which Durable Function pattern is appropriate?
- A Function chaining
- B Fan-out/fan-in
- C Human interaction (external events) (correct answer)
- D Monitor pattern
Shortcut: The human interaction pattern uses WaitForExternalEvent() to pause orchestration indefinitely until an external event (approval, rejection) is raised via the Durable Task API or HTTP.
