The Idempotency Nightmare in AI Pipelines: Data Loss and Recovery

In this post, I'll share an "idempotency" issue I recently faced in an AI-powered data processing pipeline, which led to both time and data loss, and how I resolved it. I'll try to convey through my own experiences how critical idempotency can be, especially in error scenarios, as it's one of the subtle details we might overlook when building such systems. What is Idempotency and Why is it Important? Idempotency means that an operation, when executed multiple times, yields the same result.
