From Coarse to Fine-Grained: Traffic Shaping Strategies for Million‑QPS Queues

A bulk coupon‑sending job overwhelmed a million‑QPS system, revealing that message queues only buffer but do not shape traffic; the article dissects three failure points, compares leaky‑bucket and token‑bucket rate limiters, evaluates placement on producer, broker or consumer, and progresses from static limits to adaptive shaping with handling of throttled messages.
