High Performance MySQL

A coworker handed me a copy of High Performance MySQL by Jeremy D. Zawodny and Derek J. Balling. The book (published by O'Reilly) has a publish date of 2004. I haven't found an updated edition. My question is how reliable is the information at this time?

For example, the author's make the statement "MySQL will only ever use one index per table query". I开发者_如何学Pythons this still true?
