RDB: Cloud Music's Customized Algorithm Feature KV Storage System Based on RocksDB

To meet Cloud Music’s massive algorithm‑feature KV storage needs, the team built RDB—a RocksDB‑based engine within Tair—adding bulk‑load, dual‑version imports, KV‑separation, in‑place sequence appends and protobuf field updates, cutting storage cost, write amplification and latency while scaling to billions of records and millions of QPS.
