Welcome to the MySQL source code documentation.This documentation covers primarily the MySQL server, for the mysqld process.

Other programs, like the MySQL Router, are also documented, see the Server tools section.

The order chosen to present the content is to start with low level components, and build upon previous sections, so that code is presented in a logical order.

For some sections, a full article (Doxygen 'page') presents the component in detail.

For other sections, only links are provided, as a starting point into the component.
