Problem

We guarantee same-day delivery on millions of SKUs, and the engine that decides which items to badge as Rocket Delivery needs fresh data every few minutes. Right now, stale features are causing us to over-promise on items that have gone out of stock or whose nearest fulfillment center is already at capacity. Design a data pipeline that keeps the feature store current.

Summary

Same-day delivery. The features have to be faster.
