Design and Implement an Idempotency Layer for Order Creation
Design and implement an idempotency layer for an order creation service. The goal is to prevent duplicate orders from being created when clients retry requests, ensuring that a given order creation request is processed exactly once, even in the face of network issues or client errors.
Constraints & Assumptions:
- Preserve the source scope; do not assume extra company-specific systems.
- Focus on interview reasoning, correctness, and operational trade-offs.
- Explain how you would validate the answer with examples, metrics, or tests.
