Can you explain what the Mongoose aggregation pipeline is?
The Mongoose aggregation pipeline is a powerful framework for processing data in MongoDB. It allows you to perform operations like filtering, grouping, and sorting data in a more efficient way.
How does it differ from regular queries?
Unlike regular queries, which return documents directly, the aggregation pipeline processes data through a series of stages, allowing for more complex transformations and computations.
Can you give me an example of an aggregation pipeline?
Sure! An example pipeline might include stages like $match
to filter documents, $group
to aggregate data, and $sort
to order the results.
What are some common use cases for the aggregation pipeline?
Common use cases include generating reports, analyzing data trends, and transforming data for analytics.
