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.

Redis Optimization for Vivo Push Platform: Architecture, Bottlenecks, and Solutions

To sustain Vivo Push Platform’s massive real‑time traffic, engineers re‑architected two Redis clusters, trimmed capacity by 58 %, split clusters, randomized hotspot‑prone keys, and introduced three‑level caching, cutting peak CPU load by 15 %, halving response time and improving overall Redis efficiency during peak loads.
