case class Lookup(from: String, localField: String, foreignField: String, as: String) extends PipelineOperator with Product with Serializable

_Since MongoDB 3.2:_ Performs a left outer join to an unsharded collection in the same database to filter in documents from the "joined" collection for processing. https://docs.mongodb.com/v3.2/reference/operator/aggregation/lookup/#pipe._S_lookup

from

the collection to perform the join with

localField

the field from the documents input

foreignField

the field from the documents in the from collection

as

the name of the new array field to add to the input documents
