Baidu Canghai: Unified MetaDB & Aries Foundation for Object, File & Block Storage
Baidu's Canghai storage evolves from siloed per-product systems to a unified architecture with MetaDB (distributed transactional metadata database) and Aries (scalable Blob KV data plane with online EC), using directory-aware sharding, conflict merging, Mantle path resolution, and hybrid EC/three-replica adaptation to support object, file, and block storage on one foundation.
