Hey everyone, Tobias here, the author. I am a developer fascinated by databases for over a decade and I have consumed (and still consume) everything I can find about them - including every article shared here.
When helping other developers, I see that they all struggle with creating correct database indexes for slow queries. But I could never recommend articles or books to learn it as they only discuss very simple examples or focus on super complicated stuff that is only needed by a tiny fraction of developers.
So, I wrote this book to have something I can recommend to everyone. And I did it in a completely different way:
- Focus on only practical stuff a developer needs
- Explanation of the basic principles of how indexes are used
- Examples of how all SQL operations use indexes and how they behave when combined (that's always missed in literature)
- Dozens of visualizations for an easier understanding and to replace boring walls of text

Thanks, Tobias, bought a copy, maybe I learn something that I can apply to improve the performance of my analytics app schema or indexes [0].
Based on your experience, if the proper indexes are in place, would a ~10m rows MySQL database have similar read performance to a larger, ~100m rows database, if we would aggregate over the most recent ~1m rows in both cases?
I am struggling a bit to maintain sub-second queries for databases over ~20m rows, even when the proper indexes seem to be in place.
This looks fantastic and I'd love to give it a go, but £64.55 for the epub only feels a little expensive to me. The Pragmatic Bookshelf books usually come it at around £20 for example. So I'm afraid I have to give it a miss at that price. I thought you might appreciate this feedback as I was getting out my card by the end of the page and the left when I saw the price.
Bought the book the other day and just made a start on reading it.
I have a lot of DB experience and am a massive proponent of appropriate indexing, but I know for a fact that Tobias has far more, deeper knowledge than me on this subject and am looking forward to learning some new tricks as well as getting a deeper understanding of database indexing internals
