Quadrillion-scale observability at Tesla

Mark Needham

In this fascinating video, we dive into Tesla's groundbreaking approach to observability using ClickHouse. Learn how the electric vehicle giant tackled the challenge of monitoring millions of sensors across factories, employees, and connected vehicles worldwide. We'll explore the impressive stress test that pushed ClickHouse to ingest one quadrillion rows and why Tesla chose this powerful database for their critical operations.

Key points covered:

• Tesla's five key requirements for their observability system
• Why Prometheus couldn't meet their needs and how ClickHouse stepped up
• The architecture of Tesla's Comet system, including data ingestion and querying pipelines
• Real-world metrics: tens of millions of rows ingested per second, billions of time series, and trillions of samples
• The importance of scalability and reliability in Tesla's global operations
