With version 5.7, MySQL now has over 450 settings! That gives users like you and me a lot of power and flexibility to fine-tune it to perfection. But at the same time, it leaves a lot of room for errors.

And this e-book is here to guide you through them. Take a few minutes to study them with your environment in mind and you will never look at MySQL configuration the same way.
