Scale with Redis Cluster Horizontal scaling with Redis Cluster

Redis scales horizontally with a deployment topology called Redis Cluster. This topic will teach you how to set up, test, and operate Redis Cluster in production. You will learn about the availability and consistency characteristics of Redis Cluster from the end user's point of view.

If you plan to run a production Redis Cluster deployment or want to understand better how Redis Cluster works internally, consult the Redis Cluster specification. To learn how Redis Enterprise handles scaling, see Linear Scaling with Redis Enterprise.

Reactor模式是一种处理并发请求的事件驱动设计模式，常用于高性能网络编程。它基于I/O多路复用机制，使用同步非阻塞的方式处理客户端请求。下面我将详细介绍Reactor模式的结构和工作原理。

Reactor模式的结构

Reactor模式由以下几个角色构成：

1. Reactor（反应器）：负责监听并分发事件，它是整个模式的核心。Reactor会注册和管理所有的事件处理器，并在事件到达时将其分发给对应的处理器。
