Overview of this book

PostgreSQL is the most advanced open source database in the world. It is easy to install, configure, and maintain by following the documentation; however, it’s difficult to develop applications using programming languages and design databases accordingly. This book is what you need to get the most out of PostgreSQL You will begin with advanced SQL topics such as views, materialized views, and cursors, and learn about performing data type conversions. You will then perform trigger operations and use trigger functions in PostgreSQL. Next we walk through data modeling, normalization concepts, and the effect of transactions and locking on the database. The next half of the book covers the types of indexes, constrains, and the concepts of table partitioning, as well as the different mechanisms and approaches available to write efficient queries or code. Later, we explore PostgreSQL Extensions and Large Object Support in PostgreSQL. Finally, you will perform database operations in PostgreSQL using PHP and Java. By the end of this book, you will have mastered all the aspects of PostgreSQL development. You will be able to build efficient enterprise-grade applications with PostgreSQL by making use of these concepts

Preface

Chapter 7.  Table Partitioning

In the last chapter, we talked about indexes and constraints in detail. It helped you to understand the purpose of indexes/constraints, and the best way we can use them in the real world. In this chapter, we are going to talk about table partitioning. We'll start with a basic introduction to partitioning, and will cover topics such as need for partitioning, the way it is done, and how exactly it helps. We will also discuss about the flow, that is, how it works so that you can have better control over it. You will learn how to manage table partitions once they are created, the kind of maintenance they require, and how to make the system get the best use out of it. We will also talk about types of partitioning that PostgreSQL supports, and alternative methods of partitioning. We will also discuss the impact if you do not partition a table.
