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.

Configuring the JVM

Apache Cassandra was written in Java, and therefore requires a JVM to run. Make sure to download a Java Runtime Environment (JRE) or Java Development Kit (JDK) to include as a part of your Cassandra installation. Unless otherwise noted, the latest patch of version 8 of the Oracle JDK or OpenJDK should be used.

At the time of writing, Apache Cassandra is not currently compatible with Java 9 or higher.

Adjustments to the JVM settings used by Cassandra can be made in the jvm.options configuration file. Many of those settings deal with the configuration and tuning of the garbage collector.

Garbage collection

Probably the most noticeable aspect of the JVM is how it manages garbage collection. There are two main...
