Overview of this book

MongoDB is a high-performance and feature-rich NoSQL database that forms the backbone of the systems that power many different organizations – it’s easy to see why it’s the most popular NoSQL database on the market. Packed with many features that have become essential for many different types of software professionals and incredibly easy to use, this cookbook contains many solutions to the everyday challenges of MongoDB, as well as guidance on effective techniques to extend your skills and capabilities. This book starts with how to initialize the server in three different modes with various configurations. You will then be introduced to programming language drivers in both Java and Python. A new feature in MongoDB 3 is that you can connect to a single node using Python, set to make MongoDB even more popular with anyone working with Python. You will then learn a range of further topics including advanced query operations, monitoring and backup using MMS, as well as some very useful administration recipes including SCRAM-SHA-1 Authentication. Beyond that, you will also find recipes on cloud deployment, including guidance on how to work with Docker containers alongside MongoDB, integrating the database with Hadoop, and tips for improving developer productivity. Created as both an accessible tutorial and an easy to use resource, on hand whenever you need to solve a problem, MongoDB Cookbook will help you handle everything from administration to automation with MongoDB more effectively than ever before.

Storing large data in Mongo using GridFS


A document size in MongoDB can be up to 16 MB. But does that mean we cannot store data more than 16 MB in size? There are cases where you prefer to store videos and audio files in database rather than in a filesystem for a number of advantages such as a few of them are storing metadata along with them, when accessing the file from an intermediate location, and replicating the contents for high availability if replication is enabled on the MongoDB server instances. GridFS can be used to address such use cases in MongoDB. We will also see how GridFS manages large content that exceeds 16 MB and analyzes the collections it uses for storing the content behind the scene. For test purpose, we will not use data exceeding 16 MB but something smaller to see GridFS in action.

Getting ready

Look at the recipe Installing single node MongoDB in Chapter 1, Installing and Starting the Server and start a single instance of Mongo. That is the only prerequisite for this...
