A great addition to the Redis ecosystem.

From the Foreword by Salvatore Sanfilippo, Creator of Redis

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 and internal scripting to make Redis easier to use.

About the Technology

When you need near-real-time access to a fast-moving data stream, key-value stores like Redis are the way to go. Redis expands on the key-value pattern by accepting a wide variety of data types, including hashes, strings, lists, and other structures. It provides lightning-fast operations on in-memory datasets, and also makes it easy to persist to disk on the fly. Plus, it's free and open source.

What's inside

  • Redis from the ground up
  • Preprocessing real-time data
  • Managing in-memory datasets
  • Pub/sub and configuration
  • Persisting to disk

About the reader

Written for developers familiar with database concepts. No prior exposure to Redis or other NoSQL databases required. Appropriate for systems administrators comfortable with programming.

About the author

Dr. Josiah L. Carlson is a seasoned database professional and an active contributor to the Redis community.
