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.

Installing the RethinkDB module


Usually, platforms such as Node.js are simple and minimal by design; this is why most of these platforms have some sort of system that allows you to download, install, and manage third-party extension packages called modules. For example, in Python, you have pip or easy install. In Node, you have NPM—the Node Package Manager.

NPM is both a package manager to install and remove modules from the system and a standard to define dependencies on other packages. It also provides a public registry service that contains all the Node.js modules that developers want to publish through NPM.

The RethinkDB module is also hosted on NPM, and we will use Node's package manager to install it.

Before attempting to install the module, you should check to see if NPM is installed on your system. If you have installed Node.js by following the instructions in the previous section of this chapter, you will already have NPM installed on your machine. If, however, you have installed Node...
