Mastering MongoDB 6.x - Third Edition

By: Alex Giamas

Overview of this book

MongoDB is a leading non-relational database. This book covers all the major features of MongoDB including the latest version 6. MongoDB 6.x adds many new features and expands on existing ones such as aggregation, indexing, replication, sharding and MongoDB Atlas tools. Some of the MongoDB Atlas tools that you will master include Atlas dedicated clusters and Serverless, Atlas Search, Charts, Realm Application Services/Sync, Compass, Cloud Manager and Data Lake. By getting hands-on working with code using realistic use cases, you will master the art of modeling, shaping and querying your data and become the MongoDB oracle for the business. You will focus on broadly used and niche areas such as optimizing queries, configuring large-scale clusters, configuring your cluster for high performance and availability and many more. Later, you will become proficient in auditing, monitoring, and securing your clusters using a structured and organized approach. By the end of this book, you will have grasped all the practical understanding needed to design, develop, administer and scale MongoDB-based database applications both on premises and on the cloud.

MongoDB Stable API

Starting from version 5, MongoDB introduced the Stable API. The Stable API provides a guarantee that the API will not break for client-server communication. The Stable API is declared when using any driver or the mongosh shell, in a similar fashion to the following mongosh example:

--apiVersion 1

Note

1 is the only API version available as of MongoDB 6.0.

StableAPI guarantees backward compatibility between MongoDB server upgrades.

This means that we can continue upgrading our MongoDB server without any significant risk that our application connected to the MongoDB server will behave differently.

This guarantee holds correct under the following three constraints:

  • We need to declare apiVersion in the client
  • We need to use a supported version of the official MongoDB client
  • We can only use commands and features that are supported in this API version

Following the third constraint, as of apiVersion=1, we can only use any of...
