What is redis cluster?
Redis cluster is a distributed "distributed", fault-tolerant "fault-tolerant" Redis implementation. The functions that the cluster can use are a subset "subset" of the functions that ordinary stand-alone Redis can use.
Redis cluster is a distributed, fault-tolerant Redis implementation. The functions that can be used by the cluster are those that can be used by ordinary stand-alone Redis. A subset of functions.
There is no central node or proxy node in the Redis cluster. One of the main design goals of the cluster is to achieve linear scalability.
Redis Cluster provides a way to run Redis where data is automatically partitioned across multiple Redis nodes. Redis Cluster also provides a level of availability during partitioning, which is the ability to continue running even if some nodes fail or cannot communicate. However, if a major failure occurs (for example, when most masters are unavailable), the cluster will stop functioning.

Implementing Redis cluster using ThinkPHP6
Jun 20, 2023 am 08:36 AM
With the rapid development of the Internet, the problem of high concurrency has become more and more prominent. In response to this problem, the emergence of Redis has become an important solution. It solves the problem of excessive reading and writing pressure in traditional relational databases through memory reading and writing. However, single-node Redis still has performance bottlenecks under high concurrency conditions, so Redis clusters need to be used. This article will describe how to use ThinkPHP6 to implement a Redis cluster. 1. Introduction to Redis Cluster Redis Cluster is an official cluster provided by Redis.

How to implement cluster deployment of PHP data cache through Redis? Introduction: When PHP applications face high concurrency and large traffic, they often encounter database performance bottlenecks. At this time, using caching technology can greatly improve the performance and concurrency of the system. As a high-performance in-memory key-value database, Redis is widely used in the implementation of caching solutions. This article will introduce how to implement cluster deployment of PHP data cache through Redis to further improve performance and scalability. 1. Overview of Redis Cluster Redis

Cluster solution for Redis and Node.js: How to achieve high availability Introduction: With the rapid development of the Internet, data processing has become increasingly large and complex. In order to ensure high availability and scalability of the system, we need to use a distributed cluster architecture to handle the needs of storing and processing large amounts of data. Redis, as a high-performance in-memory database, combined with Node.js as the back-end programming language, can build a highly available distributed cluster solution. This article will introduce how to use Redis and Node.js to implement
Redis cluster in Redis and how to use PHP

Redis is a high-performance open source memory data storage service. It is increasingly favored by developers because of its fast read and write speed, persistent storage and support for multiple data structures. As the business continues to grow, the storage capacity of Redis can no longer meet the demand, and it needs to be expanded. This article will introduce the Redis cluster expansion plan and its implementation details. The concept of Redis cluster Redis cluster refers to connecting multiple Redis instances together to form a large set of Redis instances, which can improve Redis
