Bilibili Configuration Center (Config & Paladin): Architecture, Features, and Performance

Bilibili’s Config Center evolved from the 2017 Config v1 monolith—offering unified UI, MySQL storage, and long‑polling—to the Raft‑based Paladin v2, which adds lifecycle management, tenant isolation, incremental publishing, high‑throughput caching, multi‑active deployment, validation and rich tooling, handling hundreds of thousands of configs and tens of thousands of concurrent clients with sub‑50 ms push latency while planning deeper K8s integration.
