Designing Partitions for Millions of QPS: From Default Settings to Precise Capacity Planning

The article explains why partition count is not a simple integer but the solution of a multi‑constraint capacity‑planning equation, walks through three design stages—from naïve defaults, through CPU‑core‑based heuristics, to a precise engineering model that balances throughput, ordering, scaling, fault domains and storage costs for million‑plus QPS workloads.
