Redis is an innovative data tool that offers more flexibility than other available NoSQL key-value stores like Cassandra or DynamoDB. Because Redis accepts hashes, strings, lists, and other structures as values, you can expand the key-value idea to a wider range of use cases. Redis works with in-memory datasets to provide lightning-fast response times, and makes it easy to persist data to disk on the fly. It's free, open source, and easy to utilize from most standard programming languages.

Redis in Action introduces Redis and walks you through examples that demonstrate how to use it effectively. You'll begin by getting Redis set up properly and then exploring the key-value model. Then, you'll dive into real use cases including simple caching, distributed ad targeting, and more. You'll learn how to scale Redis from small jobs to massive datasets. Experienced developers will appreciate chapters on clustering Redis and internal scripting to make programming for Redis it easier to use.

Dr. Josiah L Carlson is well known as an active and helpful contributor on the Redis mailing list. He has given talks about real-world uses of Redis, including building a self-service ad network, prioritizing task queues, web spiders, a Twitter analytics platform, real-time search engines, and more.
