Mastering Apache Cassandra

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>

Priam – managing large clusters on AWS


Cassandra is probably the best example of out-of-bound success of the community-driven open source project. Netflix contributes heavily to Cassandra projects. Netflix's cluster management tool, Priam, simplifies the administration of large clusters over Amazon Web Service's EC2 cloud platform. Unfortunately, detailed discussion on Priam is out of the scope of this book. The wiki page of the project is not extensive either.

Priam is a Java-based web application, primarily for the following tasks:

  • Token assignment

  • Backup and restoration

  • Configuration management

  • API to query Cassandra metrics

As an advice, for a small cluster setup (say, under 25 nodes), it is suggested to stick with simple automation based on nodetool and perhaps a shell or Python script. It will keep the administration simple. Priam requires too many parameters to set it up and perhaps it is more work for smaller clusters than to manage it manually.
