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.

Redis as a preprocessor complement to ElasticSearch


ElasticSearch started off as a JSON-based frontend to Lucene. Lucene is an open source enterprise search index sponsored by the Apache Foundation that is also the core search technology for another popular search-based technology called Solr. ElasticSearch indexes JSON documents into a Lucene index and uses a custom JSON-base DSL (domain specific language) for querying the search index. ElasticSearch uses sharding and clustering techniques for scaling search to include large data sets. ElasticSearch powers searching for a number of well known websites including Netflix, The New York Times, Cisco, eBay, and Goldman Sachs.

The main sponsor of ElasticSearch, the for-profit company Elastic.co, also supports a number of other technologies that complement or build upon the ElasticSearch search index including Logstash, a log harvester that indexes logs into ElasticSearch, and Kibana, a visualization tool for ElasticSearch. Using all three together...
