We all know that Ali has experienced several major technological changes, including abandoning Oracle and Hadoop and fully embracing MySQL.
To be reasonable, in fact, Oracle+Hadoop can also support it, why should it change. Of course, it’s definitely not because Ali’s father has no money, but even if he spends tens of millions more, he still can’t completely solve the problem , and the computing power is about to run out !
Recently, I heard from an elder brother that he had used MySQL for 12 years before he began to have a clear understanding of performance optimization. In the past, the problem of frequent requests for big data was solved by asynchronous processing mechanism and the use of shared memory , but once the data relationship becomes complicated, it cannot be avoided, and we must bite the bullet and study. Every time I chat with young people in the team, it is also the database.
In order to help more development engineers and architects master the core of MySQL, the following is a technical note sharing a high-definition PDF version of MySQL notes compiled by Ali engineers , involving all aspects of mysql, and the content quality is particularly high.
Due to space limitations, the screenshots are not shown here. Friends who need to get the full version of the MySQL notes organized by Ali engineers : [ Click here directly ] to get it for free! !
