Designing Data Intensive Applications 2nd edition (oreilly.com)

12 out of 13 chapters are already available on the O'Reilly website in the "raw and unedited" format.

The book is scheduled for publication in February 2026, but if you have an O'Reilly subscription, you can already access the new content.

The first edition is still my favorite book about software architecture.

Everyone praises this book but it was way too dry for me to get through. I have the print edition so maybe I'll give it another try
