There is a very interesting word: in today’s world, those who get data get the world.
Visible data is very important for us, for the enterprise and for future development.
And want to “get the world”, master massive data, so the storage, read and write data database requirements will be very high. In particular, MySQL, a very common database with a wide range, is one of the technical abilities that we back-end developers must master, and MySQL is also a must-ask in the interview.
Some people may think some basic operation is to master the MySQL, yao will fur, but think of themselves as being proficient in, the interview was asked difficult technical points do not know how to answer, obviously the interviewer won’t choose less competent staff, so the real popular programmer is MySQL tuning can be done.
Enterprises have higher and higher requirements for programmers, especially large factories, which explicitly require Java programmers to have the ability to tune MySQL.
With the development of the Internet, businesses, large and small, will only face more and more data. As a result, whether it is interview questions or work, just limited to the basic use of MySQL is not enough to meet the needs of the industry. So, if we want to keep up with the industry trends and not be eliminated, we must master MySQL tuning.
Industry trends affect our programmers advanced direction, for MySQL tuning ability training, however, we often is not enough, unable to do want to skillfully mastering a skill, must through the real practice, however, obviously, we can’t have vast amounts of data to practice alone, project experience, that how to solve these problems?
In order to solve this difficult problem in practice, I would like to recommend the “MySQL Performance Optimization Pyramid”, which will be optimized from the basis, case and tool sections, in-depth analysis of related concepts and principles from the work of application scenarios, comprehensive summary and answer questions on MySQL performance optimization. Take you through the actual combat to master MySQL tuning skills!
