Mastering MongoDB 3.x

By: Alex Giamas

Overview of this book

MongoDB has grown to become the de facto NoSQL database with millions of users—from small startups 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 maintainable by DevOps teams. The book is based on MongoDB 3.x 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 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 on-premise or in the cloud. We deal with database internals in the next 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.

Pluggable storage engines

With MongoDB breaking out from the web application paradigm into domains with different requirements, storage has become an increasingly important consideration.

Using multiple storage engines can be seen as an alternative way to using different storage solutions and databases in our infrastructure stack. This way, we can reduce operational complexity and development time to market with the application layer being agnostic of the underlying storage layer.

MongoDB offers four different storage engines at the moment, which we will examine in further detail in the next sections.

WiredTiger

As of version 3.2, WiredTiger is the default storage engine and also the best choice for most workloads. By providing...
