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.

Accessing MongoDB over REST


In this recipe, we will see how to access MongoDB and perform CRUD operations using REST APIs. We will use spring-data-rest for REST access and spring-data-mongodb to perform the CRUD operations. Before you continue with this recipe, it is important to know how to implement the CRUD repositories using spring-data-mongodb. Refer to the Developing using spring-data-mongodb recipe in this chapter to know how to use this framework.

The question one must be having is, why is a REST API needed? There are scenarios where there is a database that is being shared by many applications and is possibly written in different languages. Writing JPA DAO or using spring-data-mongodb is good enough for Java clients but not for clients in other languages. Having APIs locally with the application doesn't even give us a centralized way to access the database. This is where REST APIs come into play. We can develop the server-side data access layer and the CRUD repository in Java—spring...
