Overview of this book

<p>Apache Cassandra is the perfect choice for building fault tolerant and scalable databases. Implementing Cassandra will enable you to take advantage of its features which include replication of data across multiple datacenters with lower latency rates. This book details these features that will guide you towards mastering the art of building high performing databases without compromising on performance.</p> <p>Mastering Apache Cassandra aims to give enough knowledge to enable you to program pragmatically and help you understand the limitations of Cassandra. You will also learn how to deploy a production setup and monitor it, understand what happens under the hood, and how to optimize and integrate it with other software.</p> <p>Mastering Apache Cassandra begins with a discussion on understanding Cassandra’s philosophy and design decisions while helping you understand how you can implement it to resolve business issues and run complex applications simultaneously.</p> <p>You will also get to know about how various components of Cassandra work with each other to give a robust distributed system. The different mechanisms that it provides to solve old problems in new ways are not as twisted as they seem; Cassandra is all about simplicity. Learn how to set up a cluster that can face a tornado of data reads and writes without wincing.</p> <p>If you are a beginner, you can use the examples to help you play around with Cassandra and test the water. If you are at an intermediate level, you may prefer to use this guide to help you dive into the architecture. To a DevOp, this book will help you manage and optimize your infrastructure. To a CTO, this book will help you unleash the power of Cassandra and discover the resources that it requires.</p>

The required software


Cassandra runs over a JVM, and this is all you need to get Cassandra up and running. Any platform that has the JVM can have Cassandra. At the time of writing, Java's latest version was Java SE 7. However, it is highly recommended to use Oracle Java 6 for Cassandra, to avoid unexplainable bugs due to any inconsistency in the Java version or vendor implementation.

The other thing that one should consider for the production setup is to have the Java Native Access (JNA) library. It provides access to the native platform's shared libraries. JNA can be configured to disallow swapping JVM, and hence, improving Cassandra memory usage.

Installing Oracle Java 6

The default installation of Linux systems usually contains the OpenJDK Java Runtime Environment (JRE). This should either be removed or you can keep OpenJDK, but set the default JRE as Oracle JRE. This guide will assume a 64-bit system. To check whether your system has JRE, and what version of it executes, run the java -version...
