O'Reilly Releases Understanding MySQL Internals: Explore the Inner Workings of a Powerful Database
Sebastopol, CA--MySQL's source code is open in the sense of being publicly
available, but unless you understand it, it's essentially closed to you.
In Understanding MySQL Internals (O'Reilly, US $49.99), Sasha Pachev, a
former member of the MySQL development team, provides a comprehensive tour
of MySQL 5 that reveals the inner workings of this powerful database.
You'll go right to the heart of MySQL to learn how data structures and
convenience functions operate, how to add new storage engines and
configuration options, and much more.
"I do not believe it is possible to understand and appreciate MySQL
strictly through a conceptual discussion," says Pachev. "On a high
conceptual level, MySQL is very simple. It does not implement many
revolutionary designs. It sticks to the basics. Why is it so popular
The reason, he asserts, is that what makes a good database is not so much
the concepts behind it, but how well they are implemented. As important as
it is to be conceptually sound, a good portion of the genius is in
implementing those concepts in a way that provides a reasonable
combination of good performance and ease of maintenance. "In other words,
the devil is in the details," says Pachev, "and MySQL developers have done
a great job of taking that devil by the horns and twisting his head off.
"Thus, in order to appreciate the inner workings of MySQL," he continues,
"You need to get close to the places where that devil is being subdued."
Pachev's book will lead you into those very places. Understanding MySQL
Internals begins with a brief architecture overview that explains how the
different components of MySQL work together. Next, you'll learn steps for
setting up a working compilable copy of the code that you can change and
test at your convenience, and then you'll work with basic frameworks for
adding your own configuration variables (the controls of the server) and
your own storage engine.
Other sections of the book cover:
- Core server classes, structures, and API
- The communication protocol between the client and the server
- Configuration variables, including a tutorial and code for adding your
- Thread-based request handling and how threads are used in MySQL
- An overview of MySQL storage engines
- The storage engine interface for integrating third-party storage engines
- The table lock manager
- The parser and optimizer that execute SQL commands
- Integrating a transactional storage engine into MySQL
- The internals of replication
With descriptions of key data structures and methods not documented in the
source code, Understanding MySQL Internals offers you unprecedented
opportunities to learn about the inner workings of this enterprise-proven
database. Whether you're a developer, DBA, database application
programmer, software vendor, or computer science student, this is your
guide to discovering and improving a great database.
Sasha Pachev, a member of the MySQL development team from 2000 to 2002, was the original developer of replication in MySQL. The author of MySQL Enterprise Solutions (Wiley), he currently lives in Provo, Utah, and works
as an independent consultant with an emphasis on MySQL. Sasha is also a
dedicated long-distance runner and author of FastRunningBlog.com.
