Detailed explanation of consistent hashing algorithm implemented by Redis

Consistent Hashing Algorithm is widely used in distributed cache, load balancing and other scenarios, which can effectively improve the performance and scalability of the system. Among them, Redis, as a popular in-memory database, also uses consistent hashing algorithms to achieve data distribution and load balancing. This article will provide a detailed analysis of the consistent hashing algorithm from the perspective of Redis implementation. Introduction to Consistent Hash Algorithm Consistent Hash Algorithm was first proposed by David Karger

Application of Redis in container network and service grid

With the advent of the cloud native era, container technology is becoming more and more widely used. The dynamic and flexible nature of containers makes the use of container technology in cloud environments increasingly popular. In order to better manage and deploy containers, service mesh technology emerged as the times require. Service mesh allows developers to perform traffic control and security monitoring on microservices, making the deployment and maintenance of microservices easier. In the service grid, Redis is widely used as a high-performance data storage technology. It provides distributed cache, memory data storage, message queue

Redis persistence: introduction and differences between RDB and AOF

Redis is a non-relational database that is mainly based on memory storage, which makes Redis perform well in scenarios with high concurrency and high read and write speed requirements. However, because Redis stores data in memory, after the server crashes or restarts, the data previously stored in the memory will be cleared and the data will not be persisted, which may cause serious data loss problems. In order to solve this problem, Redis provides a persistence mechanism, mainly using two strategies: RDB and AOF. This article will introduce Redis in detail
