GpuHashAggregateExec

case class GpuHashAggregateExec(requiredChildDistributionExpressions: Option[Seq[Expression]], groupingExpressions: Seq[NamedExpression], aggregateExpressions: Seq[GpuAggregateExpression], aggregateAttributes: Seq[Attribute], resultExpressions: Seq[NamedExpression], child: SparkPlan, configuredTargetBatchSize: Long, configuredTieredProjectEnabled: Boolean, estimatedPreProcessGrowth: Double, forceSinglePassAgg: Boolean, allowSinglePassAgg: Boolean) extends SparkPlan with ShimUnaryExecNode with GpuExec with Product with Serializable

The GPU version of SortAggregateExec that is intended for partial aggregations that are not reductions and so it sorts the input data ahead of time to do it in a single pass.

requiredChildDistributionExpressions

this is unchanged by the GPU. It is used in EnsureRequirements to be able to add shuffle nodes

groupingExpressions

The expressions that, when applied to the input batch, return the grouping key

aggregateExpressions

The GpuAggregateExpression instances for this node

aggregateAttributes

References to each GpuAggregateExpression (attribute references)

resultExpressions

the expected output expression of this hash aggregate (which this node should project)

child

incoming plan (where we get input columns from)

configuredTargetBatchSize

user-configured maximum device memory size of a batch

configuredTieredProjectEnabled

configurable optimization to use tiered projections

    A goal to coalesce batches as the input to this operation. In some cases an operation will only work if all of the data is in a single batch. In other cases it may be much faster if it is in a single batch, but can tolerate multiple batches. This provides a way to express those desires.
