Mastering Redis

By: Jeremy Nelson

Overview of this book

Redis is the most popular, open-source, key value data structure server that provides a wide range of capabilities on which multiple platforms can be be built. Its fast and flexible data structures give your existing applications an edge in the development environment. This book is a practical guide which aims to help you deep dive into the world of Redis data structure to exploit its excellent features. We start our journey by understanding the need of Redis in brief, followed by an explanation of Advanced key management. Next, you will learn about design patterns, best practices for using Redis in DevOps environment and Docker containerization paradigm in detail. After this, you will understand the concept of scaling with Redis cluster and Redis Sentinel , followed by a through explanation of incorporating Redis with NoSQL technologies such as Elasticsearch and MongoDB. At the end of this section, you will be able to develop competent applications using these technologies. You will then explore the message queuing and task management features of Redis and will be able to implement them in your applications. Finally, you will learn how Redis can be used to build real-time data analytic dashboards, for different disparate data streams.

Clustering Redis with Twemproxy

Twemproxy is an open source project released by Twitter for creating a caching proxy between a client and backend made up of either Memecache or Redis instances. Twemproxy separates the client calls, in our case any suitable Redis client, from the datastore backend through the use of an intermediary middleware. This middleware then implements a sharding strategy based on your preferences that are set in a configuration YAML file. Twemproxy supports twelve different hash functions including md5, crc16, two versions of crc32, four variants of the Fowler-Noll-Vo (FNV), among others with the default being a fnv1a_64 hash functions.

With Twemproxy being a C program such as Redis, the steps to get Twemproxy running require a couple of different methods. To get started quickly, go to and download Twempoxy's distribution tarball. (You can also download a source tarball or clone the repository with Git, both requiring the...
