7. Data Aggregation

Overview

This chapter introduces you to the concept of aggregation and its implementation in MongoDB. You will learn how to identify the parameters and structure of the aggregate command, combine and manipulate data using the primary aggregation stages, work with large datasets using advanced aggregation stages, and optimize and configure your aggregation to get the best performance out of your queries.

Introduction

In the previous chapters, we learned the fundamentals of interacting with MongoDB. With these basic operations (insert, update, and delete), we can now begin exploring and manipulating our data as we would with any other database. We also observed how, by fully leveraging the find command options, we can ...
