Design and Optimization of Bilibili Log Service 2.0 Using ClickHouse and OpenTelemetry
Bilibili’s Log Service 2.0 replaces its Elastic‑Stack pipeline with an OpenTelemetry‑driven architecture that writes logs via high‑performance Go/Java SDKs to ClickHouse, delivering ten‑fold write throughput, two‑fold query speed, one‑third storage cost, a custom query gateway, visualization UI, and advanced alerting.
