1 Million QPS Coupon‑Grab System: Distributed Rate Limiting, Stock Capping, and CAP Trade‑offs

The article explains how a production‑grade coupon‑grab service can survive millions of requests per second by treating rate limiting as a business admission layer, separating stock capping from throttling, making explicit CAP trade‑offs, and implementing a hybrid Redis‑based token‑bucket limiter with local fallback, monitoring, and deployment best practices.

How to End Duplicate Consumption in RocketMQ with Idempotence and High‑Concurrency Architecture

The article explains why RocketMQ inevitably delivers duplicate messages under at‑least‑once semantics, analyzes root causes in producer, broker and consumer stages, and presents a production‑grade idempotent solution that combines business keys, Redis caching, Redisson locks, a MySQL idempotent table, AOP interception, and comprehensive monitoring to guarantee exactly‑once business outcomes even under high concurrency and Kubernetes graceful shutdown.
