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>

Stress testing


Before you start to claim the performance numbers of your Cassandra backend based on numbers that you have read elsewhere, it is important to perform your own stress testing. It is very easy to do that in Cassandra as it provides special tooling for stress testing. It is a good idea to customize the parameters of the stress test to represent a use case that is closer to what your application is going to do. And this will save a lot of heated discussion later due to discrepancies in the load test and the actual throughput that the software is able to pull out of the setting.

The load test tool is found under the Cassandra installation directory under tools as tools/bin/cassandra-stress. Here are some useful parameters:

-d, --nodes: CSV list of nodes to run the queries against-o, --operation: Operation to perform, default: insert-R, --replication-strategy: Replication strategy, def: Simple-O, --strategy-properties: in <dc>:<RF>,<dc1>:<RF1> format-U, --comparator...
