PostgreSQL 12 High Availability Cookbook: Over 100 recipes to design a highly available server with the advanced features of PostgreSQL 12, 3rd Edition

by Shaun M. Thomas

A comprehensive guide to understanding key techniques for architecture and hardware planning, monitoring, replication, backups, and decoupling Databases are nothing without the data they store. In the event of an outage or technical catastrophe, immediate recovery is essential. This updated edition ensures that you will learn the important concepts related to node architecture design, as well as techniques such as using repmgr for failover automation. From cluster layout and hardware selection to software stacks and horizontal scalability, this PostgreSQL cookbook will help you build a PostgreSQL cluster that will survive crashes, resist data corruption, and grow smoothly with customer demand. You'll start by understanding how to plan a PostgreSQL database architecture that is resistant to outages and scalable, as it is the scaffolding on which everything rests. With the bedrock established, you'll cover the topics that PostgreSQL database administrators need to know to manage a highly available cluster. This includes configuration, troubleshooting, monitoring and alerting, backups through proxies, failover automation, and other considerations that are essential for a healthy PostgreSQL cluster. Later, you'll learn to use multi-master replication to maximize server availability. Later chapters will guide you through managing major version upgrades without downtime. By the end of this book, you'll have learned how to build an efficient and adaptive PostgreSQL 12 database cluster. This book is for Postgres administrators and developers who are looking to build and maintain a highly reliable PostgreSQL cluster. Although knowledge of the new features of PostgreSQL 12 is not required, a basic understanding of PostgreSQL administration is expected.

About the author

Shaun was born in 1977 in Olympia, WA with a major congenital heart defect. Until his corrective surgery in 1984, he could partake in very little physical activity due to lack of oxygen. This set the stage for him to become an avid reader.

After a short obsession with Forgotten Realms, Stephen King, and Melanie Rawn, he started writing a trilogy in 1994 that was unfortunately shelved due to the academic demands of the I.B. Program, later continuing with those of a double major in Mathematics and Computer Science at Cornell College. It's possible he'll revise the old notes and storyline and complete the series, but his new Phase Cycle currently demands most of his attention. The first book in this series, Rabbit Rue, first appeared on Shaun's publishing site, and was later published by Smashwords for offline reading as an eBook.

Shaun currently lives in the Chicago area with his wife Jennifer, who plans to start Ph.D. work in elementary music education in 2011.
