Mastering PostgreSQL 10

Overview of this book

PostgreSQL is an open source database used for handling large datasets (big data) and as a JSON document database. This book highlights the newly introduced features in PostgreSQL 10, and shows you how you can build better PostgreSQL applications, and administer your PostgreSQL database more efficiently. We begin by explaining advanced database design concepts in PostgreSQL 10, along with indexing and query optimization. You will also see how to work with event triggers and perform concurrent transactions and table partitioning, along with exploring SQL and server tuning. We will walk you through implementing advanced administrative tasks such as server maintenance and monitoring, replication, recovery, high availability, and much more. You will understand common and not-so-common troubleshooting problems and how you can overcome them. By the end of this book, you will have an expert-level command of advanced database functionalities and will be able to implement advanced administrative tasks with PostgreSQL 10.

Partitioning data

Given default 8 k blocks, PostgreSQL can store up to 32 TB of data inside a single table. If you compile PostgreSQL with 32 k blocks, you can even put up to 128 TB into a single table.

Starting with PostgreSQL 10.0, we have improved partitioning, which will offer end users significantly easier handling of data partitioning.

In this chapter, the old means of partitioning as well as the new features available as of PostgreSQL 10.0 will be covered.
