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>

CQL 3 basics


This section is a brief introduction to CQL 3 on Cassandra 1.1.x. We will see queries and discuss options available. For more formal query definitions, please refer to the Cassandra CQL 3 documentation that is appropriate for the Cassandra version that you are using. One of the good sources for this is the Apache CQL 3 documentation and the DataStax Cassandra documentation. Most of the queries that are mentioned here should work in 1.1.x as well as in 1.2.x versions, but the queries are not tested against 1.2.x and further versions.

The CREATE KEYSPACE query

Creating keyspace just requires keyspace name, strategy class, and options for the specific strategy class as mandatory elements. Keyspace name has the same restrictions as Java variable naming has. Keyspace names should be alpha-numeric and they must start with...
