The aggregation pipeline is one of MongoDB's most powerful features. It allows you to perform complex data processing directly in the database.
Stage Optimization
Order your stages carefully to minimize the amount of data being processed. Filter your results early with $match and $project.
Facets for Analytics
The $facet stage allows you to perform multiple aggregations on the same set of input documents in a single stage, which is perfect for building analytics dashboards.
