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.

Revisiting nodetool

Much of this chapter will focus on using Apache Cassandra's nodetool utility. As mentioned previously, the nodetool utility installs with Cassandra, and is central to most aspects of cluster management. Before we get too far into discussing it, there are some important things to note about nodetool:

  • It uses port 7199 for JMX.
  • Remote JMX access must be explicitly enabled within each node's configuration.
  • Without remote JMX, you will need to SSH into the node to utilize it in nodetool.
  • Nodetool is separate from Apache Cassandra. Different versions of nodetool can communicate with different versions of Cassandra, so use it with caution.
