## AI overview

This case study describes how Tesla built Comet, a large-scale observability platform on ClickHouse. The system was designed to ingest tens of millions of rows per second, retain data for years, support real-time analysis and anomaly detection, and meet demanding availability and scalability requirements. The article explains why Tesla moved beyond Prometheus and highlights a quadrillion-row load test.
