Youzan ID Generator Multi-Room Solution

Youzan redesigned its ID generator to run independent March instances per room, sharing a single etcd cluster but allocating distinct, non‑overlapping ID ranges via boundary, lower, and upper parameters, enabling room‑level high availability, horizontal scaling, and zero‑downtime migration with automated tooling.
