The third edition is nearly done. I’ve committed first drafts of all chapters, and all but one appendix. I need to do the last appendix and then rewrite the preface, which is a few days of work at my current pace. After that, it’s the usual tech review, copyediting, updates to figures, etc—and then it’s off to production.
I’m really pleased with this edition. I was planning on it just being a refresh of the second edition to reflect what’s new in MySQL-land, but it’s almost a complete rewrite. There’s a lot more focus on a logical approach throughout: what happens in the server, what are the limitations, why this matters, what are the practical consequences and applications, and therefore…. The “and therefore” is the real reason you buy a book such as this one.
