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.

Executing query and insert operations using a Java client

In this recipe, we will look at executing the query and insert operations using the Java client for MongoDB. Unlike the Python programming language, Java code snippets cannot be executed from an interactive interpreter, and thus we will be having some unit test cases already implemented, whose relevant code snippets will be shown and explained.

Getting ready

For this recipe, we will start a standalone instance. Refer to the Installing single node MongoDB recipe from Chapter 1, Installing and Starting the Server for instructions on how to start the server.

The next step is to download the Java project, mongo-cookbook-javadriver, from the Packt website. This recipe uses a JUnit test case to test out various features of the Java client. In this whole process, we will use some of the most common API calls and thus learn to use them.

How to do it…

To execute the test case, one can either import the project in an IDE-like Eclipse and execute...
