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.

Replica set configurations


We have had a good discussion on what replica set is in Chapter 1, Installing and Starting the Server in the recipe Starting multiple instances as part of a replica set, and we saw how to start a simple replica set. In the recipe Interprocess security in Mongo in this chapter, we saw how to start a replica set with interprocess authentication. To be honest, that is pretty much what we do in setting up a standard replica set. There are a few configurations that one must know and should be aware of how it affects the replica set's behavior. Note that we still are not discussing tag aware replication in this recipe and it would be taken up later in this chapter as a separate recipe Building tagged replica sets.

Getting ready

Refer to the recipe Starting multiple instances as part of a replica set in Chapter 1, Installing and Starting the Server for the prerequisites and know about the replica set basics. Go ahead and set up a simple three-node replica set on your computer...
