GeneratedAggregate

Instance Constructors

new GeneratedAggregate(partial: Boolean, groupingExpressions: Seq[Expression], aggregateExpressions: Seq[NamedExpression], unsafeEnabled: Boolean, child: SparkPlan)

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.
unsafeEnabled
whether to allow Unsafe-based aggregation buffers to be used.
child
the input data source.
