+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.
