Learn any language or technology because they have unique uses. Let’s first talk about the power of redis. Why should you choose to learn redis?
First of all, Redis is known as the fastest database in history, and there is no need to re-change the original relational database (our original database is Mysql).
Secondly, Redis can use the transaction function. Don’t underestimate the transaction function. It can ensure that a series of user business processes are unified.
Once again, in order to ensure network bandwidth, we used the pipeline function. This function can transmit a bunch of commands to Redis at once, reducing network overhead.
Finally, the persistence of Redis is a very important mechanism. Although Redis is fast, its speed depends on it running in memory. Once an accident occurs or a power outage occurs, important information may be lost. At this time, persistence comes into play.
After joining Redis, we quickly discovered that Redis, which was originally just to reduce customer service pressure, later supported the main caching architecture of our business and became an important part of the project process.
So how to learn redis? Is redis difficult to learn? (redis tutorial)
In "Getting Started with Redis to Distributed Practice", we will explain how to learn and use redis with the correct posture. Let's take a look at the arrangement
Why we To use Redis
Here will be a systematic introduction to what Redis is and its functions that eight major Internet companies are concerned about;
Understanding and use of API
There are 7 APIs for Redis These seven data types can help you better use different business scenarios;
How to use Redis client
Redis has prepared clients in various languages for you. . This time we will explain the use of the commonly used Redis client in Java and Python to help you learn to use it first.
Advanced functions of Redis
Not only do you need to use Redis, but you also need to understand the advanced functions of Redis. These functions have better support for different businesses and help you use redis more efficiently. .
Correct understanding of Redis persistence and development and operation and maintenance issues
Here we will introduce to you the most important persistence of Redis, so as not to lose data and some of the most common problems in daily development and operation and maintenance.
Redis replication that must be learned for high-availability operation and maintenance
We often encounter information transfer between different databases to ensure data consistency. At this time, the Redis replication function is particularly special in the production environment. important.
Redis Sentinel Deployment and Operation and Maintenance
Of course there cannot be only one server in the production environment. In order to ensure the integrity of the data, we need to back up the data. In this way, after the server hangs, it can be quickly restored.
Redis Cluster distributed solution
This is the distributed architecture officially provided to us, which allows you to allocate different machines according to certain rules according to different data. At the same time, when the amount of data exceeds the server hard disk, we can expand the server again.
Cache design and optimization: As we all know, for a large number of data queries, we do not query the database directly, but let Redis query the cache first when the client requests it, and then check the database when it does not exist.
