Keep in mind that node.js is primarily used to build high-performance, highly scalable server and client applications, and it is geared toward "live Web".The goal of Node.js is to provide an "easy way to build scalable Web servers", which is impacted by event machines from the Ruby language (events Machine) and the twisted framework from Python. Redis is an open source, with the use of ANSI C language, sup

Gradual, from easy to difficult, so that more fun. Overview This article began to continue on the basis of the content, this article mainly introduces Spring-session implementation configuration using Redis cluster, there will be two ways to configure, one is Redis-cluster, one is Redis-sentinel, and through a simple demo demo for example. For

Redis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), and Zset (ordered collection). These data types support Push/pop, Add/remove, and intersection-set and difference sets, and richer operations, and these operations are atomic. Based on this, Redis supports sorting in a variety of different ways. As with m

In some cases, Redis keeps keys/values in memory to improve the efficiency of data queries and data modifications, but this is not always a good choice. In view of this, we can further

Reproduced in: http://www.itxuexiwang.com/a/shujukujishu/redis/2016/0216/133.htmlFirst, overview:Sorted-sets and sets types are very similar, both are collections of strings and do not allow duplicate members to appear in a set. The main difference between them is that each member of the sorted-sets has a fraction (score) associated with it, and Redis is sorting the members of the collection from small to l
