Problem
We're a logistics company delivering parcels across 18,000 pin codes in India, and every scan at a warehouse, vehicle, or delivery point is a tracking event. Our customers expect real-time shipment status, and our ops team needs to know when parcels are stuck or moving in the wrong direction. The problem is that scan events arrive out of order - a parcel can be scanned at delivery before we've received the confirmation it left the origin hub. Design a pipeline that maintains accurate shipment state despite these ordering issues.
Summary
Out for delivery. Delivered. Except the events arrived backwards.
