A data engineering journey from basic to advance topics
Format: Kindle
Is the third time that I read this book. One of the most valuable aspects is the fact that depending of your data engineering mature, you'll always find a new aspect or ideas to put in practice. Hope the second version come soon!

Lottery Book
Format: Paperback
This book contains a lot of opinions without facts. Some are true, some are not. But its a lottery, you cold pick a gold text or a text that is full of buzzwords, without any meaning, fact and useless in real life.

Glad I bought this used
Format: Paperback
It’s packed with buzzwords and adjectives, offering plenty of in-vacuum advice and self-promotional ‘hire-me’ vibes. There’s some real insight here, but it’s buried under a lot of noise.

Not useful
Format: Paperback
This book has a few pieces of good advice, but its buried under mountains of weird and amateur level musings. Example: Paul Singman advocates for eliminating ETL entirely. How? Just reprogram the applications to which you may or may not have the source code to handle your data processing. He calls Intention Data Transfer 🥴 Thanks for the advice Paul, I'll get right on that.
