Four benefits of using mysql8

1. The default utf8mb4, have not encountered the problem of character set class (unless manually changed to other character set)

 

2. Permanent settings, don't worry about the configuration reset after the server restarts.

For example, to modify the default length of group_concat, you can set PERSIST group_concat_max_len=1024000;

 

3. Simple sorting function, no need to manually write @variables for sorting

rank() over(partition by field to be separated according to order by field to be sorted according to it)'rank'

 

4. Support json, I have not used it, but my colleagues say it is easy to use
