case class Group(identifiers: BSONValue)(ops: (String, GroupFunction)*) extends PipelineOperator with Product with Serializable

Groups documents together to calulate aggregates on document collections. This command aggregates on arbitrary identifiers. Document fields identifier must be prefixed with $. http://docs.mongodb.org/manual/reference/aggregation/group/#_S_group

identifiers

Any BSON value acceptable by mongodb as identifier

ops

Sequence of operators specifying aggregate calculation.
