Aggregate

case class Aggregate(partial: Boolean, groupingExpressions: Seq[Expression], aggregateExpressions: Seq[NamedExpression], child: SparkPlan)(sqlContext: SQLContext) extends SparkPlan with UnaryNode with NoBind with Product with Serializable

:: DeveloperApi :: Groups input data by groupingExpressions and computes the aggregateExpressions for each group.

partial

if true then aggregation is done partially on local data without shuffling to ensure all values where groupingExpressions are equal are present.

groupingExpressions

expressions that are evaluated to determine grouping.

aggregateExpressions

expressions that are computed for each group.

child

the input data source.
