The examples on this page demonstrate how to use the MongoDB Query API in a function to aggregate documents in your Atlas cluster. MongoDBaggregation pipelinesrun all documents in a collection through a series o
The MongoDB Aggregation framework, which is part of the Query API, is modeled on the concept of data processing pipelines. Documents enter a pipeline that contains one or more stages, and this pipeline transforms the documents into an aggregated result. Aggregation operations function similarly to ...
Learn about the $sort aggregation operator, which sorts all input documents and returns them to the pipeline in sorted order.
