Problem
We run a large e-commerce site with web and mobile apps. We capture every click, page view, and product interaction as raw events. Users browse from multiple devices, and we need to stitch their activity into sessions and build a complete picture of the purchase journey. We get about 600 million events per day. Design the data model.
