Overview

Dive into a comprehensive tutorial on the MongoDB Aggregation Framework, exploring its powerful features and capabilities. Learn how to load sample documents, understand the aggregation process, and master various aggregation stages including $match, $group, $count, $sort, $project, $limit, and $unwind. Discover how to work with arrays, use accumulators like $sum and $avg, and apply unary operators such as $type. Gain practical experience through numerous examples that demonstrate how to combine different stages for complex data transformations. Explore advanced topics like the $out stage for writing results to a new collection and the allowDiskUse option for handling large datasets. By the end of this 1.5-hour tutorial, you'll have a solid grasp of MongoDB's aggregation framework and be able to perform sophisticated data analysis and manipulation tasks.
