title: Book review: "Database Internals"

I'm now reading the "Database Internals" book, by Alex Petrov. I'm liking it a
lot, and I have a similar feeling at the end of each chapter of when I was
reading "Designing Data-Intensive Applications": each chapter has some
references to other books, articles and resources, and I feel like I should go
and reach all of them to have a deeper understanding of the subject.
It gives just enough historical background in the text itself to show that the
author does have knowledge in this area.
# Chapter 1: Introduction and Overview
The covering of basic vocabulary (column vs wide-column) is very good and
straightforward, and the fundamental trade-offs are shown very clearly, like
in-memory and disk-based storage, primary-keys and offset lookups, etc.
Finishing this chapter I was happy with it's content and looking forward for a
more in-depth tour of many of the concepts presented here.
