Mastering Apache Cassandra 3.x - Third Edition

By: Aaron Ploetz, Tejaswi Malepati, Nishant Neeraj

Overview of this book

With ever-increasing rates of data creation, the demand for storing data fast and reliably becomes a need. Apache Cassandra is the perfect choice for building fault-tolerant and scalable databases. Mastering Apache Cassandra 3.x teaches you how to build and architect your clusters, configure and work with your nodes, and program in a high-throughput environment, helping you understand the power of Cassandra as per the new features. Once you’ve covered a brief recap of the basics, you’ll move on to deploying and monitoring a production setup and optimizing and integrating it with other software. You’ll work with the advanced features of CQL and the new storage engine in order to understand how they function on the server-side. You’ll explore the integration and interaction of Cassandra components, followed by discovering features such as token allocation algorithm, CQL3, vnodes, lightweight transactions, and data modelling in detail. Last but not least you will get to grips with Apache Spark. By the end of this book, you’ll be able to analyse big data, and build and manage high-performance databases for your application.

Scaling down

Needing to scale down a cluster isn't a terribly common task. But sometimes a cluster uses more resources than it needs, due to application retirement or migration. This is especially true in the case of deploying into a public cloud, where extra compute comes with a price tag. In this case, being fiscally responsible with your company's money often translates into trimming down your cluster's resources for efficiency.

Removing nodes from a cluster

The most obvious way to trim resources is to remove nodes from the cluster. Sometimes, nodes may need to be removed after crashing on their own. In a cloud environment built with efficient DevOps processes, it is often much faster to re-provision a troublesome...
