Redis distributed lock implementation (1) - Best Code Paper

WebWe propose an algorithm, called Redlock , which implements a DLM which we believe to be safer than the vanilla single instance approach. We hope that the community will analyze … WebThe killer feature of Redis is that it allows you to perform atomic operations on individual data structures, like counters, lists, and sets. The atomic part is HUGE. Using an ORM wrapper that retrieves a "record", updates values, then sends those values back, removes the atomicity, and thus the major advantage of Redis. Just use MySQL, k? difference between force and impulse

Web1. std::atomic atomic 클래스는 정수형 또는 포인터 타입에 대해 산술 연산들을 atomic하게 수행할 수 있도록 해 주는 템플릿 클래스이다. (더하고 빼고, 그리고 and/or/xor 등의 비트 연산들...) 이전에는 atomic 연산을 하기 위해서는 volatile 변수와 interlocked 계열 함수를 일일히 사용해 주어야 했지만, WebAPI的情况下将redis改造成多线程。KeyDB将redis原来的主线程拆分成了主线程和worker线程。解析协议之后每个线程都会去操作内存中的数据，由一把全局锁来控制多线程访问内存数据。在worker线程数组中下标为0的就是主线程。在redis中所有链接管理都是在一个线程中完成 … difference between for and to in grammar
