1. Introduction to RedisRedis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and HASHS (hash type). These

The add by Zhj:redis does not have an absolute advantage over memcached compared to the performance. We use Redis because it supports more data types, and when the memory allocated to Redis is full,Redis also does not delete data that is not expired,

First, what is redis? Redis is a memory-based, persistent log-type, key-value database high-performance storage system that provides APIs in multiple languages. Second, Background Data structure requires more and more data structures,

Redis master-slave Construction Structure: 1). the same master can synchronize multiple slaves.2). Server Load balancer can also accept connections and synchronization requests from other Server Load balancer instances. This effectively distributes

Recently, redis encountered multiple concurrent processing of the same cache. In this case, the locking mechanism is required. I wanted to use the readwritelock that comes with Java to set the read/write lock. This is also the method used by the

I. redis Memory Management Redis is a memory-based Key-value database, and its memory management is very important. In order to shield the differences between different platforms and count the memory usage, redis encapsulates memory allocation

Hiredis is the C interface of redis database. Currently, it can only be used in Linux. Several Basic functions can be used to operate redis database.   Function prototype: rediscontext * redisconnect (const char * IP, int port) Description: This

Maybe you have heard of the script language embedded in redis, but haven't you tried it yourself? This tutorial will help you learn how to use the powerful Lua language on your redis server. Hello, Lua!Our first redis Lua script returns only one

Redis is actually a dictionary structure, and key ----> value is a typical dictionary structure. [Of course, for vaule, there are different memory organizational structures. This is not the case]Imagine a storage scenario like this: Key:

1. dict There are two main problems: 1. Hash conflicts. The solution is zip. Typedef struct dictentry {void * key; Union {void * val; uint64_t u64; int64_t s64 ;}v; struct dictentry * Next;} dictentry; Next field zip 2. rehash during resizing,
