Seamless Migration of Xianyu Product Database Using TDDL and DTS
Xianyu migrated its tens‑billion‑row product database from a shared MySQL cluster to an isolated instance by refactoring with dual‑write, employing TDDL for sharding and sequence management, and using Alibaba Cloud DTS for full‑load, incremental sync, consistency verification, and a no‑data‑loss rollback, achieving seamless, user‑transparent migration and improved stability.
