This is a great post—clear, practical, and grounded in a real production incident, which makes the lessons very easy to trust. I really like the move to async processing with Redis-backed idempotency; it feels like the right long-term solution rather than a quick patch, especially at scale with Shopify webhooks. I’d be very interested to see how this setup behaves under even higher load or with additional event types, as this pattern seems broadly reusable.
Thank you for the thoughtful feedback—I really appreciate you taking the time to dig into both the incident and the solution. Your point about reusability is encouraging, and exploring this pattern under higher load and more event types is definitely an exciting next step.
Really solid post—this is a clear, honest breakdown of a real production issue and the fix feels both pragmatic and scalable. The shift to idempotency plus async processing is exactly what I’d expect for Shopify webhooks at this scale, and the measurable results make the solution feel very credible. I’d love to see a follow-up diving deeper into the Redis key strategy or how you handle edge cases during partial failures.
Thank you so much—really appreciate the thoughtful feedback and encouragement. I’m glad the approach resonated, and a deeper dive into the Redis key strategy and failure edge cases sounds like a great idea for a follow-up.
This is an excellent example of treating webhook delivery as an unreliable system. The idempotency approach with Redis is clean and production-ready.
Absolutely! I really appreciate how you tackled this—your Redis-based idempotency solution is both elegant and practical for real-world production. Truly inspiring work!
Solid FastAPI + Celery architecture. Simple, understandable, and scalable — no unnecessary abstractions.
Really appreciate the clear separation between acknowledgment and background processing. This is exactly how webhook consumers should be designed.
Thanks for the great insight—your approach to separating acknowledgment from background processing is spot on and shows strong engineering judgment. It’s a clean, scalable pattern and a solid example others can confidently follow.
The post-mortem style makes this incredibly practical. Not enough articles show real failures and fixes like this.
Totally agree — this kind of honest post-mortem is incredibly valuable. Sharing real failures and concrete fixes like this helps the whole community learn and improve.
