Poor wording on my part. My point isn't about performance, it's about API. Other than selecting documents from single collection (.find), Mongo's queries are shockingly wierd and inconsistent to me. Compare aggregation framework to what SQL has, for example: https://docs.mongodb.com/manual/reference/sql-aggregation-comparison/ https://docs.mongodb.com/manual/reference/sql-aggregation-co... Or even within Mongo, querying and aggregating are astonishingly different things, that you need to learn separately. And then there are JOINS. And stale reads with other serialization issues.
