Type Members

  1. case class BoundJoinExprs(boundBuildKeys: Seq[GpuExpression], buildTypes: Array[DataType], boundStreamKeys: Seq[GpuExpression], streamTypes: Array[DataType], streamOutput: Seq[Attribute], boundCondition: Option[GpuExpression], numFirstConditionTableColumns: Int, compareNullsEqual: Boolean, buildSideNeedsNullFilter: Boolean) extends Product with Serializable

    Utility class to track bound expressions and expression metadata related to a join.

  2. class HostHostJoinSizer extends SymmetricJoinSizer[SpillableHostConcatResult]

    Join sizer to use when both the left and right table are coming directly from a shuffle and the data will be on the host.

    Join sizer to use when both the left and right table are coming directly from a shuffle and the data will be on the host. Caches shuffle batches in host memory while probing without grabbing the GPU semaphore.

  3. class JoinInfo extends AnyRef

    Utility class to track information related to a join.

  4. class SpillableColumnarBatchJoinSizer extends SymmetricJoinSizer[SpillableColumnarBatch]

    Join sizer to use when at least one side of the join is coming from another GPU exec node such that the GPU semaphore is already held.

    Join sizer to use when at least one side of the join is coming from another GPU exec node such that the GPU semaphore is already held. Caches input batches on the GPU.

  5. trait SymmetricJoinSizer[T <: AutoCloseable] extends AnyRef

    Trait to house common code for determining the ideal build/stream assignments for symmetric joins.
