"HP Vertica Essentials" book review

I have recently decided that it is a good idea to show you some books that I read and share my opinion about them with you. So here I want to introduce you to a book about HP Vertica named "HP Vertica Essentials", written by Rishabh Agrawal. I have worked with HP Vertica in the past and have done some setup operations, querying and aggregation. I read only official docs, so when I saw this book about HP Vertica, I decided to read it. First of all I want to point out that this book is mostly for DBAs, but some chapters would be interesting for developers too. If you're a DBA and would like to know more about Vertica or at least want to know how to setup a Vertica server to play with, then you can read the book.
