Preface
Needless to say, MySQL is the most active and popular open source database. Because of its low cost and easy operation, it is widely used in Internet companies, even the top BATJ. It can be seen from this that if you want to be successful in the Internet industry, or if you want to enter first-line Internet companies such as BATJ, then mastering MySQL must be a necessary stepping stone.
For the use of MySQL, many developers who are just starting to work are still quite unfamiliar, but if they want to learn and don't know where to start, the backwardness of technology will naturally make people feel anxious. In fact, learning MySQL can be easily done by finding the right method.
Today, I will share with you the "million-level" MySQL notes compiled by Huawei bosses. From basics to optimization to architecture, it will take you easy to get started with one click.
If you need to get it, you can get it for free after one-click and three-connection. Look at the assistant's v: (bjmsb10) add it and get it for free.

to sum up
What will the future look like? I have no way to predict. Maybe you say that big data is the trend and artificial intelligence is the trend, but no one of us knows what it will be like ten years later. It is said that programmers after the age of 30 will be anxious, but no matter what industry you are in, if you don't catch it for a few years, you will also be anxious after 30.
Therefore, if you are not a person who explores the future, then you must be a person who stands firmly at the top of the pyramid. This million-level MySQL notebook may help you get one step closer to your dream.
