Bigger than it sounds when you're live coding it.
Start by clarifying requirements and constraints, then outline a modular pipeline with separate stages for parsing, fetching, saving, and converting. Discuss trade-offs like error handling, idempotency, and performance, and finally provide a concise code sketch or pseudocode to demonstrate implementation.
Pro tip: Emphasize idempotency and retry logic with exponential backoff for POST requests, as Stripe values reliability and fault tolerance in integrations. Also, mention using context managers for file operations to ensure resources are properly released.
Ask about the API's authentication, rate limits, expected data volume, and error handling requirements. Confirm whether the pipeline should be idempotent and how failures should be handled.
Break down the pipeline into distinct stages: JSON parsing, POST requests for resource fetching, binary image saving, and timestamp conversion. Ensure each stage is loosely coupled and testable.
Incorporate retries with exponential backoff for POST requests, validate responses, and handle exceptions gracefully. Use context managers for file I/O to prevent resource leaks.
Use a robust datetime parsing library (e.g., dateutil) to convert string timestamps to datetime objects, handling timezone awareness and format variations.
Talk about trade-offs between synchronous vs asynchronous requests, memory usage for large images, and idempotency keys for POST requests. Suggest logging and monitoring for production readiness.
