YouTube Data Pipeline Design Flow | Interview Preparation #shorts

Product based companies conduct one dedicated interview round for data pipeline design ????‍???? Real-time Data Pipeline Design For YouTube Creator Dashboard ???? ➤ 1. Real-time data sources • YouTube apps/web send live events (watch, heartbeat, stop) • Backend services push likes, comments, subscribes • Live streaming services push concurrent viewers & chat events All events are continuously generated. ⸻ ➤ 2. Ingestion layer (real-time pickup) • Events are published to Kafka / PubSub / Kinesis • Separate streams like watch_events, engagement_events • Handles millions of events per second • Buffers traffic spikes and supports replay This is the entry point of the real-time pipeline. ⸻ ➤ 3. Stream processing layer • Flink / Spark Structured Streaming consumes streams • Cleans and validates events • Deduplicates events • Applies real-time aggregations (per minute, per creator, per video) • Outputs ready-to-serve real-time metrics This is the real-time brain of the system. ⸻ ➤ 4. Serving layer (powering the dashboard) • Hot store (Redis / Dynamo / Cassandra) – Used for instant dashboard tiles – “Views now”, “Watch time last 5 min”, “Top videos now” • Analytics store (ClickHouse / Druid / BigQuery) – Used for charts and breakdowns – Trends, geo, device, traffic source • API layer – Reads from hot store for speed – Reads from analytics store for charts This layer directly powers the creator dashboard. ⸻ ➤ 5. Reliability & replay • Raw events also land into a data lake • Used for backfills, fixes, audits, and recomputation • Ensures long-term correctness ——— ????
