Redis core technology and practice: learning summary directory

1 Redis Learning path

stay 《Redis Core technology and actual combat 》 In the course of learning , I often see a class representative speak , He is Kaito, He summed up a Redis Learning path brain map （ Recommended collection ）, take Redis The knowledge of is divided into categories , Help us form a knowledge system .

below , I will refer to the above brain map to integrate the Redis Study, summarize and sort out , I hope it helps you .

2  Data structure and basic usage

Basic data type

• Redis Infrastructure and 5 Large underlying data structures

• List Type the underlying data structure ： Compressed list 、 Double linked list And Quick list

• String Type of extreme case ： be based on Hash Secondary coding of + Compressed lists combined with memory savings

Extended data types

• Redis Common extended data types ：Bitmap、HyperLogLog、GEO（ It also involves how to customize the extended data type ）

Redis Used as a MQ

• Redis Stream The basic concept and practical use of （ It involves XADD、XREAD、XREADGROUP、XPENDING + XACK And so on ）

Redis Used as cache

• Redis  Concepts and solutions of common cache exception problems （ involve The data in the cache is different from DB atypism 、 Cache avalanche 、 Cache breakdown 、 Cache penetration ）

• Redis  Cache retirement strategy （ Focus on LFU and LRU Two elimination strategy algorithms ）

Redis Used as a distributed lock

• Redis There are two ways to ensure concurrency ： Atomic manipulation And Distributed lock

• Redis Key technologies supporting seckill scenes ： Atomic manipulation And Distributed lock

3 Redis High performance and high reliability technology  

Single thread cognition

• Redis The core point of single thread ： Basic cognition 、 Why single thread 、 Why is it so efficient ？

Multithreading cognition

• Redis 6.0 New characteristics ： Multinetwork IO Threads （NOTE： Read / write command processing is still single threaded ）

Troubleshooting and resolution of slow performance

• Redis The performance of the 5 The big factor , How to check Redis Slow down （ Focus on Redis Key system configuration ）

Persistence mechanism

• AOF、RDB And Mix persistence Key points

Master slave replication mechanism

• Master slave library read / write separation mode Of   Overall mechanism and The basic flow

Sentinel mechanism

• The concept and mechanism of sentry and sentry cluster （ The sentinel monitoring mechanism is involved 、 Principle of selecting main database 、 The core operating mechanism of the cluster ）

Cluster slicing

• Redis Cluster Cluster slicing （ The cluster implementation mechanism is involved And The solution of two core problems ）

• Codis vs Redis Cluster（ The comparison of the two schemes ）

4 Redis Usage specifications and industry practices

Standard use specification

• One copy Redis Standard use specification （ Key value pair usage specification 、 Command usage specifications , mandatory / recommend / Suggest , Recommended must see ）

Microblogging Redis practice

• Sina Weibo is right Redis Do the optimization of the （ Meet high performance 、 Share the practices of large manufacturers with high concurrency and large capacity storage requirements ）

5 Summary

Redis Our learning journey has come to an end for the time being ,Edison It started again Kafka Learning journey , On the way to study , Be curious + Keep taking notes , And then start Practise, Time will give us the answer ！
