Design and Implementation of Bilibili Object Storage Service (BOSS): Architecture, Topology, Metadata, Erasure Coding, and Scaling
The article chronicles Bilibili’s 13‑day development of BOSS, a custom object storage service, detailing how it replaces MySQL‑based routing and ID generation with replicated etcd or Raft KV stores, models metadata via protobuf, adopts erasure coding and a Bitcask‑style engine, and implements safe delete, replica repair, and horizontal scaling for a resilient large‑scale system.
