Overview of this book

PostgreSQL is one of the most powerful and easy to use database management systems. It has strong support from the community and is being actively developed with a new release every year. PostgreSQL supports the most advanced features included in SQL standards. It also provides NoSQL capabilities and very rich data types and extensions. All of this makes PostgreSQL a very attractive solution in software systems. If you run a database, you want it to perform well and you want to be able to secure it. As the world’s most advanced open source database, PostgreSQL has unique built-in ways to achieve these goals. This book will show you a multitude of ways to enhance your database’s performance and give you insights into measuring and optimizing a PostgreSQL database to achieve better performance. This book is your one-stop guide to elevate your PostgreSQL knowledge to the next level. First, you’ll get familiarized with essential developer/administrator concepts such as load balancing, connection pooling, and distributing connections to multiple nodes. Next, you will explore memory optimization techniques before exploring the security controls offered by PostgreSQL. Then, you will move on to the essential database/server monitoring and replication strategies with PostgreSQL. Finally, you will learn about query processing algorithms.

Preface

Setting up a Postgres-XL cluster


Here in this recipe, we are going to set up a Postgres XL cluster, which is a scalable PostgreSQL cluster, to solve the big data processing challenges.

Getting ready

Postgres-XL is a horizontally scalable open source cluster, which has a set of individual dedicated components to scale PostgreSQL to multiple nodes. Postgre-XL (extensible lattice) gives us more convenience in distributing the data across the nodes or replicating the data across the nodes.

How to do it...

Note that:

node1 -- ec2-54-164-174-117.compute-1.amazonaws.com -- 172-30-1-154
node2 -- ec2-54-152-235-194.compute-1.amazonaws.com -- 172-30-1-155
node3 -- ec2-54-165-7-151.compute-1.amazonaws.com -- 172-30-1-156
node4 -- ec2-54-152-210-130.compute-1.amazonaws.com -- 172-30-1-157
  1. Create the PostgresXL user account and group:

            sudo groupadd pgxl
            sudo useradd -g pgxl pgxl
    
  2. Install RPMS on all four servers. Copy the following RPMS to the server and make sure you are in the same location...
