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.

Backing up and restoring data

Apache Cassandra provides the ability to take a snapshot of all SSTable files on a node. The resulting snapshot files are essentially hard links or pointers to these files. Combining snapshots with the incremental backup feature helps to ensure that lost data can be restored in a quick and timely manner. For more information, refer to the Backing up and restoring data section of the Cassandra documentation, available at https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsBackupRestore.html.

Taking snapshots

Snapshots can be taken system-wide, or focused on a single keyspace or table. Invoking a snapshot is done very easily with nodetool. To take a snapshot for all tables in a specific...
