How ClickHouse runs ClickHouse: observability at quadrillion-row scale

ClickHouse Cloud's massive-scale observability platform (200+ PB, 30+ regions): multi-cloud architecture, cross-regional querying, queue-free OTel ingestion, and secure AI agent access to telemetry.

A deep dive on how we built our internal observability platform for ClickHouse Cloud running at huge scale (200+ PB, 1+ quadrillion rows, 30+ regions) covering the multi-cloud ClickHouse architecture.

We cover how we enable cross-regional querying, cost-effective OpenTelemetry ingestion without traditional queuing infrastructure, and practical patterns for giving AI agents secure access to sensitive observability telemetry.
