Problem

Our food delivery platform wants to show restaurant partners which dishes are trending in their city right now. A dish is trending when its order rate over the last 30 minutes is significantly higher than its baseline. We want this updated every few minutes. Design the data pipeline that powers this dashboard.

Summary

The dish rankings update faster than the kitchen.
