Rezension bezieht sich auf: PostgreSQL Replication (Kindle Edition)
After I've had some experience with replication in a broader manner, and a bit more with various other relational Database Management systems, I got a job on my favourite DBMS, PostgreSQL. I bought this book not as a layman and my expectations were accordingly. This book is not a complete documentation about all configuration options, I did not expect. It is also not a complete survey of all possible products available on the topic, this I think rather impossible within open source products. But something I was not expected is, that this book reviews the most essential theoretical basics, everyone should know on replication. Further, the book is guiding through a series of rather practical configuration schemes, all with working examples. At that point, I found it much like a textbook for some university lectures, written in a clear and understandable style, giving the necessary theoretical background to the practical, working example.
On the other hand, authors describe some 3rd party products, e. g. pgPool2, and how to utilise them in PostgreSQL replication, but the description is limited to the most basic configuration cases without any practical point of view for large scale installations. Also, I was missing a summary of the examples, which could provide a view to the complete setup. The Kindle edition, which I've bought, suffers from some layout issues with tables and code snippets, nevertheless, it is still good readable.
All in all, I would recommend this book to all, to those who will have a first touch with replication as well, as to those who have already experiences on the topic. This book could be a good entry and will help understand the many other configuration options.
