From Random to Intelligent: Partition Selection Strategies for 10 Million QPS Systems

The article walks through four generations of partition‑selection strategies—from naive random and round‑robin to key‑hash, sticky, and finally intelligent load‑aware routing—explaining how hotspot keys, batch inefficiency, consumer skew, and fault amplification threaten stability at 10 M QPS and offering concrete engineering actions to design, test, monitor, and switch strategies in large‑scale message‑queue deployments.
