Getting Started with RethinkDB

By: Gianluca Tiepolo

Overview of this book

RethinkDB is a high-performance document-oriented database with a unique set of features. This increasingly popular NoSQL database is used to develop real-time web applications and, together with Node.js, it can be used to easily deploy them to the cloud with very little difficulty. Getting Started with RethinkDB is designed to get you working with RethinkDB as quickly as possible. Starting with the installation and configuration process, you will learn how to start importing data into the database and run simple queries using the intuitive ReQL query language. After successfully running a few simple queries, you will be introduced to other topics such as clustering and sharding. You will get to know how to set up a cluster of RethinkDB nodes and spread database load across multiple machines. We will then move on to advanced queries and optimization techniques. You will discover how to work with RethinkDB from a Node.js environment and find out all about deployment techniques. Finally, we’ll finish by working on a fully-fledged example that uses the Node.js framework and advanced features such as Changefeeds to develop a real-time web application.

Developing web applications with Node.js


In the previous chapter, you learned all about Node's key features that make it a great choice when writing highly-performing software and when you need to interact with a database. You'll be happy to know that Node.js is also a great choice when you want to build real-time web applications.

Node.js allows you to build modern, real-time web applications that use a module called Socket.io that implements WebSockets, allowing you to push data asynchronously from the server to the clients. This technology, combined with RethinkDB's Changefeeds, allows you to build web applications that send data to the clients in real time without all the complexity and downfalls of traditional real-time programming flows, such as continuously polling the server for updates.

When developing web applications, most languages and platforms provide you with frameworks that greatly simplify the job of writing TCP or HTTP servers. For example, the most popular framework for...
