Insert a document to inventory db.inventory.insertone ( { " id" : 1, "item" : "abc1", sizes: [ "s", "m", "l"] } ) the following aggregation uses the $unwind stage to output a document for each element in the sizes array: db.inventory.aggregate ( [ { $unwind : "$sizes" } ] ) what is the output?.

Mongodb Aggregation The book provides practical, easy to digest principles and approaches for increasing your effectiveness in developing aggregation pipelines, supported by examples for building pipelines to solve complex data manipulation and analytical tasks. In this paper, we will deep dive into mongodb’s aggregation framework and look into the diferent stages of the aggregation pipeline. we’ll see how we make use of these stages in an aggregation process. Aggregation the documents and return computed results. it collects values from documents, groups them together and then performs different types of operations on that grouped data like sum, average, minimum. Translate map reduce operations to aggregation pipelines for improved performance and usability, using operators like `$group` and `$merge`.
