CreateViewCommand class

createView command.

Creates a view as the result of the applying the specified aggregation pipeline to the source collection or view. Views act as read-only collections, and are computed on demand during read operations. You must create views in the same database as the source collection. MongoDB executes read operations on views as part of the underlying aggregation pipeline.

The view definition pipeline cannot include the $out or the $merge stage. If the view definition includes nested pipeline (e.g. the view definition includes $lookup or $facet stage), this restriction applies to the nested pipelines as well.

The command accepts the following fields:

db Db The database on which create the collection
view String The view name to be created.
source String The name of the source collection or view from which to create the view. The name is not the full namespace of the collection or view; i.e. does not include the database name and implies the same database as the view to create. You must create views in the same database as the source collection.
pipeline List

An array that consists of the aggregation pipeline stage(s). db.createView creates the view by applying the specified pipeline to the source collection or view.

The view definition pipeline cannot include the $out or the $merge stage. If the view definition includes nested pipeline (e.g. the view definition includes $lookup or $facet stage), this restriction applies to the nested pipelines as well.

The view definition is public; i.e. db.getCollectionInfos() and explain operations on the view will include the pipeline that defines the view. As such, avoid referring directly to sensitive fields and values in view definitions.
createViewOptions createViewOptions - Optional a set of optional values for the command
rawOption Map An alternative way to creteViewOptions to specify command options (must be manually set)
