GeneratedAggregate

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

:: DeveloperApi :: Alternate version of aggregation that leverages projection and thus code generation. Aggregations are converted into a set of projections from a aggregation buffer tuple back onto itself. Currently only used for simple aggregations like SUM, COUNT, or AVERAGE are supported.

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.
