1 Redis Introduction and InstallationRedis is an open source, advanced key-value Storage and a perfect solution for building high-performance, scalable Web applications.The three main features that Redis inherits from its many competitions are:Redis The database is completely in memory and the disk is used for persistence only. Redis has a rich set of data types

The preface has just written a comparison of three popular products in NoSQL, this time writing about some things about Redis, the introduction of Redis, installation and extension (Php-redis, because I am phper) installation and so on. It is also written to my friends (CCCJJJZ) as well as to my own later installation use.Table of Contents 1.

If the key is modified between the Watch () and exec () calls, batch processing of the final exec () execution will fail. Through some experiments, the effect of this fun

accepting foreign write requests# Min-slaves-to-write 3# Min-slaves-max-lag 10If there is greater than or equal to 3 connections from Redis with a delay greater than 10 seconds, then the master Redis will no longer accept external write requests. If one of the two configurations is set to 0, this feature will be turned off4. Safety (Security)############################# SECURITY ##########################

3.2.3 HyperloglogsRedis added the Hyperloglog algorithm in version 2.8.9.3.2.4 Publish/Subscribe featureA Redis Publish Subscription (PUB/SUB) is a message communication pattern: the Sender (pub) sends a message and the Subscriber (sub) receives the message. Redis clients can subscribe to any number of channels.Subscribe to a channel on a client redis

Similar to memcached, But it solves the problem that data is completely lost after power-off, and she supports more undefined value types. Besides string, it also supports lists (linked list), sets, and zsets. These data types support pus

nodes Cluster can continue to work when some nodes are hung or unreachable TCP ports for Redis clusters Each node in the Redis cluster needs to establish 2 TCP connections and listen to these 2 ports: One port is called the "client Port", which is used to accept client instructions, interact with the client, such as 6379, and the other port is called "Cluster bus port", which adds 10000 to

If PONG is returned, the connection is successful. Directly press redis-cli to enter the

single thread, even if the cache-flush-delay is set to 0, multiple clients need to wait in queue for simultaneous writing, if the queue capacity exceeds the cache-max-memory redis design, it enters the waiting state, causing the caller to get stuck. On Google group, enthusiastic netizens quickly completed the stress test. When the memory is used up, the processing speed of set per second dropped from 25

Introduction to Redis:First, IntroductionRedis is an open source, Key-value database that is written in C and that supports network interaction and can be persisted based on memory. Redis source code is very simple, as long as there is time to see rectification C language, to see the source of Redis can read 50-60%. The current largest cluster of Redis should be
