The Limit in MongoDB can be used with the find() method to limit the number of documents returned from a collection, or with the aggregate() method to limit the number of documents returned by an aggregation pipeline. The Limit in MongoDB is useful for improving query performance and reducing network overhead when working . I'm not 100% sure how the ordering of this. My end goal is to replicate this SQL: SELECT DISTINCT ON (group_id) FROM group_members. WHERE user_id in [1,2,3] ORDER_BY last_post_at DESC. LIMIT 5. I'm wondering how to make it performant for a very large group_members and still return it in the right order. I'm attempting to write a query to return the top X terms across each category - e.g. top 5, top 10 etc. Each term has an associated category, and based up on some help from another stackoverflow MongoDB Aggregation goes further though and can also perform relational-like joins, reshape documents, create new and update existing collections, and so on. While there are other methods of obtaining aggregate data in MongoDB, the aggregation framework is the recommended approach for most work.
Developer Data Platform. Innovate fast at scale with a unified developer experience When you perform any kind of aggregation operations in MongoDB, documents pass through what is known as the aggregation pipeline. The MongoDB aggregation pipeline is comprised of multiple stages. The documents that enter the pipeline are transformed during each stage; the results of a stage are then passed to the next stage.Atlas Documentation Get started using Atlas Server Documentation Learn to use MongoDB Start With Guides Get step-by-step guidance for key tasks. .
