About the Author
Gregory Smith is the principal consultant in the United States for international PostgreSQL services firm 2ndQuadrant. Based in Baltimore, MD, he's been providing database advice to clients in industries like manufacturing, finance, and web development for twenty years. Dedicated to open-source technology since early in his career, Greg turned to full-time PostgreSQL work by diving in at the source code level. He contributes regular feature patches to the core database and has written a variety of database tools. This book reflects the perspective that he's gained over the last few years as one of the most prolific sources of advice on the popular PostgreSQL community mailing lists.
Top Customer Reviews
If desired, you can read just the sections you think you need to know (maintenance, indexes, high performance queries), but it isn't a long or difficult read. If you work with Postgres, and don't currently know what tuple refers to in that context, I highly encourage you to read the entire book. Full disclosure: I strongly advocate having an understanding of the layers of abstraction beneath your project, even if you do not interface with them directly.
Most Helpful Customer Reviews on Amazon.com (beta)
What surprised me most about this book was how much of it is not specific to PostgreSQL, but in fact hardware considerations and testing that are pertinent to most relational databases. In that sense I wouldn't limit my recommendation to just PostgreSQL, but also to anyone using a relational database on Unix/Linux for a high load project.
The PostgreSQL 9 High Performance book isn't going to teach you too much about writing better queries,day to day management (which is more of the focus of the Admin Book), or how to load data etc, but it will tell you how to determine when your database is under stress or your hardware is failing and adversely affecting your queries and what is causing that stress. It will also provide rules of thumb as to how to pick the best hardware for your project and budget, how to partition your data, what disks to put what kind of data. Various tuning and benchmarking techniques for highload testing.
Provides a lot of details that help to actually understand what is going on in database. Every performance/optimization technique, configuration flag is explained in detail.
First half of the book covers thinks like choosing hardware, processor, memory, disk, file system, RAID matrix ,etc. In spite of the fact that I am java programmer, not DB engineer I find this part interesting too; it is good to know how database does its job.
Somewhat old (addresses postgreSQL 9.0 and older versions, we have 9.4 now), but I see no parts that are outdated. PostgreSQL have not changed that much (you may read release notes for 9.1-9.4) and basic principles (that are explained very well, in length and in great detail) are not to change anytime soon.
