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.

Getting ready

In this recipe, we would be simulating some operations on a standalone mongo instance by running a script that would attempt to keep your server busy, and then in another terminal we will run these utilities to monitor the db instance.

You need to start a standalone server listening to any port for client connections; in this case, we will stick to the default 27017. If you are not aware how to start a standalone server, refer to Installing single node MongoDB in Chapter 1, Installing and Starting the Server. We also need to download the script KeepServerBusy.js from Packt site and keep it handy for execution on local drive. Also, it is assumed that the...
