Handling failure in a distributed system is non-trivial and requires extra vigilance on the part of the system designers. This is especially true in a stateful, coordinated database like Cassandra. Fortunately, the architects of Cassandra have done an excellent job in building a resilient, fault-tolerant system that is designed from the ground up to be highly available.

We have covered a lot of ground in this book, from the basics of distributed database design to building scalable Cassandra data models. While not exhaustive by any means, the topics covered have hopefully helped you gain confidence as you design and deploy your Cassandra-backed applications.

As you take the next step in your journey with Cassandra, please participate by sharing your experience and learning from others. The project has a strong community of individuals and businesses who are committed to building the most scalable and resilient database in the world, and we value contribution at any level.

Thank you...
