To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I just finished "Designing Data Intensive Applications" and was looking for a book to provide some more in depth details on how to build streaming systems. I picked this up since it had good reviews and the topics looked like it fit nicely with what I wanted. I'm halfway through it and all I can really say is it's been a giant disappointment. The main author (I say main because there are 3 distinct authors) spends more time teasing what's coming later in the chapter/book than actually diving into the topics in any real depth. When the author actually gets around to talking about the nuts and bolts of designing streaming systems, the topics are presented in such a confusing way that I've had to go back and reread pages over and over before I was able to make any sense of what it was they were trying to convey. It's been a horribly frustrating experience and I'd honestly have trouble recommending this book to anyone. Take the list of topics mentioned in the glossary of the book and then go off and research those topics on your own. You'll almost certainly find less fluff and more coherent explanations with that approach.
I was looking for a practical book to understand the "beam model" and show me some "code" examples to start working this apache beam/google dataflow. This book is all about the basic principes/theory behind beam model and does it step by step, making this book a little hard to read
