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 data to GridFS from Java client


In the previous recipe, we saw how to store data to GridFS using a command-line utility that comes with MongoDB to manage large data files: mongofiles. To get an idea of what GridFS is and what collections are used behind the scenes to store the data, refer to the previous recipe Storing large data in Mongo using GridFS.

In this recipe, we will look at storing data to GridFS using a Java client. The program will be a highly scaled down version of mongofiles utility and focus only on how to store, retrieve, and delete data rather than trying to provide a lot of options like mongofiles do.

Getting ready

Refer to the recipe Installing single node MongoDB from Chapter 1, Installing and Starting the Server, for all the necessary setup for this recipe. If you are interested in more details on Java drivers, refer to the recipes Implementing aggregation in Mongo using a Java client and Executing MapReduce in Mongo using a Java client in Chapter 3, Programming...
