A comprehensive guide to understanding key techniques for
architecture and hardware planning, monitoring, replication,
backups, and decoupling Key Features Newly updated edition,
covering the latest PostgreSQL 12 features with hands-on
industry-driven recipes Create a PostgreSQL cluster that stays
online even when disaster strikes Learn how to avoid costly
downtime and data loss that can ruin your business Book
DescriptionDatabases 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.
What you will learn Understand how to protect data with PostgreSQL
replication tools Focus on hardware planning to ensure that your
database runs efficiently Reduce database resource contention with
connection pooling Monitor and visualize cluster activity with
Nagios and the TIG (Telegraf, InfluxDB, Grafana) stack Construct a
robust software stack that can detect and avert outages Use
multi-master to achieve an enduring PostgreSQL cluster Who this
book is forThis 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.
