The configuration of a database and the types of requests made by clients to it will differ from use case to use case. This means there is no one size fits all set of tuning parameters for MySQL. Use the information in this learning path as general guidance to help with tuning MySQL.
Application tuning allows you to gain performance without scaling a deployment up (bigger machines) or out (more machines). This gives the option to use the gained performance, or to trade it for cost savings by reducing the total compute resources provisioned.
All links to MySQL documentation in this learning path point to the latest version of the documentation. If you are using an older version of MySQL, be sure to change the documentation version after clicking the links.
