MongoDB has grown to become the de facto NoSQL database with millions of users, from small start-ups to Fortune 500 companies. Addressing the limitations of SQL schema-based databases, MongoDB pioneered a shift of focus for DevOps and offered sharding and replication that can be maintained by DevOps teams. This book is based on MongoDB 4.0 and covers topics ranging from database querying using the shell, built-in drivers, and popular ODM mappers, to more advanced topics such as sharding, high availability, and integration with big data sources.
You will get an overview of MongoDB and will learn how to play to its strengths, with relevant use cases. After that, you will learn how to query MongoDB effectively and make use of indexes as much as possible. The next part deals with the administration of MongoDB installations, whether on-premises or on the cloud. We deal with database internals in the following section, explaining storage systems and how they can affect performance. The last section of this book deals with replication and MongoDB scaling, along with integration with heterogeneous data sources. By the end this book, you will be equipped with all the required industry skills and knowledge to become a certified MongoDB developer and administrator.
