UberThe Dashboard and the Attribution Model
Our digital marketing platform generates a continuous stream of ad impression and conversion events that need to feed both a real-time campaign performance dashboard and a daily attribution model. We have been running separate streaming and batch pipelines that have drifted out of sync, causing discrepancies between the live dashboard and the daily report. Design a unified architecture on Azure Databricks that eliminates the discrepancy.
Ask the interviewer clarifying questions to understand the requirements and constraints before designing.
