I am considering purchasing High Performance MySQL (2008). This book discusses MySQL 5.0 and 5.1. Is this book still relevant today, or is it too old?

If you're getting a good deal on the book, go for it. The majority of the information in the book will be relevant, as the current version is 5.5 I believe. So, a major version release has not yet occurred.

There are significant differences between 5.1 and 5.5. See this page. –  Thomas Owens Nov 8 '11 at 14:46

Is this really the way you want to save few bucks?

If you are going to put in the effort go though a significant portion of the book (Hours if not days of work), and you don't already own it. Always buy the latest ver...

What are you going to save by getting the old ver, 20$?

I would be cautious using old references. The latest major version number is 5, with 5.5 being the latest GA release and 5.6 being the latest development release. A number of specific changes and incompatabilities are mentioned in the MySQL 5.5 documentation as things that have occurred between 5.1 and 5.5.

Rather than purchasing a book, I'd recommend using the online MySQL documentation for the version you have, and then asking specific questions on an appropriate site, such as Stack Overflow or Database Administrators, mentioning the version you are using.

The book is about version 5.1 as the author wrote in the title to the question. –  Jonas Nov 8 '11 at 15:17
    
@Jonas I scanned and searched the exerpt linked to. There are no references to MySQL 5.1, only 3.23 and 4.0. –  Thomas Owens Nov 8 '11 at 15:20
    
Yes, because it was just an excerpt. The 3.23 and 4.0 reference was a note about older versions. I have updated the link in the question. It is correct in the title to the question too. –  Jonas Nov 8 '11 at 15:29
    
@Jonas Updating answer now. –  Thomas Owens Nov 8 '11 at 15:30
