Hi Shuai! I think you can read MySQL source code, but you can't use any exist code of MySQL. You should use different code even new way to implement the same feature. Thanks, Lixun 2018-03-20 0:06 GMT+08:00 zhzhzoo zhang <zhzhzoo@gmail.com>:
Hello everybody,
I am a first year graduate in Peking University major in math. I started to take part in algorithm contests at grade 7 so I have a lot of programming experience and I am very well trained in algorithms and data structures. In my childhood memory MySQL was the most popular DBMS choice for personal website (LAMP stack). However it was acquired by Oracle as I grew up. In this year's GSoC projects, `optimizer trace' interested me particularly. It would be great for MariaDB to have this functionality. This functionality is already implemented in MySQL. So my question is, can I read MySQL's source code implementing this function? Would that cause legal problems? Thanks very much!
Regards,
Zhang Shuai.
