Problem

Our apps emit a constant stream of user interaction events that today land in a server log file and get thrown away. We want a clickstream pipeline that collects every event once and then serves two very different readers: the product team running funnel and feature-adoption analysis across months of history, and on-call engineers who need to pull a single device's last few hours of activity within minutes of a bug report. Design the clickstream data processing pipeline.

Summary
