Problem

Our link shortener does about 200 million redirects a day. Every redirect fires a click event and we need to serve two consumers from that stream: a real-time dashboard that shows per-link clicks within the last hour, and a nightly batch aggregate that powers the analytics API for date-range queries. Traffic is very spiky and some links go viral. Design the pipeline.

Summary

Billions of clicks. One tiny code. Two very different clocks.
