    What Is The Aggregation Framework?PipelinePipeline OperatorsBest Practices For Using The Aggregation FrameworkConclusionThe Aggregation framework is just a way to query documents in a collection in MongoDB. This framework exists because when you start working with and manipulating data, you often need to crunch collections together, modify them, pluck out fields, rename fields, concat them together, group documents by field, explode array of fields in different documents and so on. This cannot be done by the traditional querying system which MongoDB comes with (that is, the find query or update query, or any other query you mig
