Overview of this book

Apache Cassandra is a massively scalable, peer-to-peer database designed for 100 percent uptime, with deployments in the tens of thousands of nodes, all supporting petabytes of data. This book offers a practical insight into building highly available, real-world applications using Apache Cassandra. The book starts with the fundamentals, helping you to understand how Apache Cassandra’s architecture allows it to achieve 100 percent uptime when other systems struggle to do so. You’ll get an excellent understanding of data distribution, replication, and Cassandra’s highly tunable consistency model. Then we take an in-depth look at Cassandra's robust support for multiple data centers, and you’ll see how to scale out a cluster. Next, the book explores the domain of application design, with chapters discussing the native driver and data modeling. Lastly, you’ll find out how to steer clear of common anti-patterns and take advantage of Cassandra’s ability to fail gracefully.

Thrift versus the native protocol

Cassandra users fall into two general categories:

  •  Those who have been using it a while and have grown accustomed to working directly with storage rows via a Thrift-based client.
  • Those who are relatively new to Cassandra and are confused by the role Thrift plays in the modern Cassandra world.

Hopefully we can clear up the confusion and set both groups on the right path. Thrift is a remote procedure call (RPC) mechanism combined with a code generator, and for several years, it formed the underlying protocol layer for clients communicating with Cassandra. This allowed the early developers of Cassandra itself to focus on the database rather than the clients. But, as we hinted at in the introduction, there are numerous negative side effects of this strategy:

  • There was no common language to describe data models and queries, as each client implemented different abstractions on top of the underlying Thrift protocol.
  • Thrift was limited to the lowest...
