Great book. Data-Intensive Applications topic is new to me. This book served as a good introduction. It's very detailed and comprehensive. It slowly walks you step by step through different topics. The book gets overwhelming by the amount of new concepts but the author does a good job explaining it.
Unfortunately there is little knowledge I can apply to my daily work. The biggest highlight for me: distributed systems are very hard and there is no single solution, but rather the solution with the best set of compromises you can tolerate.
After reading the book, I became a bigger fan of single-leader database replication. It offers the best balance of cost, performance and complexity.
I would recommend this book to people who think they need distributed storage, because "SQL doesn't scale". Also it's a good read for senior devs who want to upskill and get an introduction to distributed systems.
