Huawei cloud MySQL cloud database can easily help data to the cloud

MySQL Database, I think my friends should be familiar with , It is by far the most popular relational database management system , stay web In terms of application , It is also one of the best application software of relational database management system ,

however , Often the first thing we come into contact with MySQL All databases are operated by a single machine , That is, just install the configuration on your own computer MySQL, Deal with project development on your computer , A little more than one user works together to develop , Stand alone so MySQL The database can't deal with , This is obviously not possible , In more cases , Our software products are all completed under the collaborative development of many programmers , What to do in this situation ？ You can't just let one person use the database on the computer , It's not going to work .

So at this time, the database can be like web Like applications, cloud operation is particularly important , The benefit of this is not only to share database resources with developers , And it can be like our web The website is the same , Operate the database in the cloud , Listen, isn't it nice？

So today, little ape comes to share with my friends a cloud operation on the database I usually like to use , Put your MySQL The database realizes cloud deployment , Want to implement cloud database , I have to mention cloud database RDS, Cloud database RDS（Relational Database Service, abbreviation RDS） It is a stable and reliable platform based on cloud computing 、 Stretch and stretch 、 Convenient online cloud database service . At present, the cloud database of Huawei cloud is often used in development RDS, The cloud database RDS The following engines are supported ：

MySQL
PostgreSQL
SQL Server
Today I'd like to share with you Huawei cloud MySQL Cloud database , Cloud database MySQL Have stable and reliable 、 Safe operation 、 Stretch and stretch 、 Easy to manage 、 It is economical and practical . Three of them are very prominent ：

The architecture is mature and stable , Support for popular applications , Applicable to many fields and industries ; Support a wide variety of WEB application , The cost is low , It is almost the first choice for small and medium-sized enterprises .
The management console provides comprehensive monitoring information , Simple and easy to use , Flexible management , Visual and controllable , So it's very easy to use .
Flexible scaling of required resources according to business conditions at any time , On demand , Make to measure , There is no need to worry about the size of your own data .
As a qualified programmer , Of course, you can't just be proficient in all kinds of CRUD operation , Of course, more is to use the thread pool operation of the database to deal with a large amount of data and when the amount of concurrency is relatively large , The multithreading operation used on the database , And is it over ？

The partners forgot about the database transaction ACID What are the four features ？“ Atomicity 、 Uniformity 、 Isolation, 、 persistence ”, you 're right ！ Often when operating the database , Don't forget the transaction operation of data and various lock operations . Faced with so many database operations , Hua Wei Yun MySQL How does cloud database deal with it ？

For these characteristics , Huawei cloud database MySQL A series of optimizations have been launched for a long time , All the above contents are covered ！ It mainly includes ：

The thread pool function is introduced , Support more connections , For large concurrency, the performance is significantly improved .
Yes MySQL 5.6 Introduce true multithreaded replication , Greatly reduce replication latency .
Support for storage engines MyISAM Automatic conversion to InnoDB, Full support for transactions , At the same time, avoid table lock , Improve concurrency , And compatible MyISAM grammar , Completely transparent to users .
Support RDS Access control , Perform permission control on commands that can affect the stable operation of the instance , Ensure that the instance is stable and reliable .

Do you think that's all you need to do ？ did not ！！！

Program apes usually need to consider the running time of the program when developing , How do we often operate ？ In program or sql Record the time before the statement is executed , Get the time after the statement is run , however , I found that Huawei cloud database MySQL There are some small features that are easy to use , For example, you can view the memory usage of each thread , increase CPU、 Rollback segment 、 Statistics of tables, indexes and other relevant information , This seemingly simple little operation , But it has played a great help to users' daily operation and maintenance ！

But for ordinary project development , The most important consideration in the use of database is the security of data 、 Integrity and reliability issues , If an enterprise's cloud database is often faced with data leakage 、 Risks such as transaction loss , So this is obviously unreliable .

So in response to this problem , Huawei cloud database MySQL It has its own highly reliable application mechanism to ensure that transactions are not lost , Ensure data integrity . At the same time, in the case of sudden power failure in the computer room, the main library will collapse , The master library can recover itself from a crash , Ensure the stability of the service at the first time . These are not satisfied by other cloud database services . So that's why I usually like to use Huawei cloud database . The most important thing is that it is easy to use and not expensive , There are often coupons for whoring for nothing , Now it's only a dozen yuan. Dare you believe it ！
