abstract class RapidsMeta[INPUT <: BASE, BASE, OUTPUT <: BASE] extends AnyRef

Holds metadata about a stage in the physical plan that is separate from the plan itself. This is helpful in deciding when to replace part of the plan with a GPU enabled version.

INPUT

the exact type of the class we are wrapping.

BASE

the generic base class for this type of stage, i.e. SparkPlan, Expression, etc.

OUTPUT

when converting to a GPU enabled version of the plan, the generic base type for all GPU enabled versions.

    wrapped

    what we are wrapping

    conf

    the config

    parent

    the parent of this node, if there is one.

    rule

    holds information related to the config for this object, typically this is the rule used to wrap the stage.

    The wrapped data writing commands that should be examined

  2. abstract val childExprs: Seq[BaseExprMeta[_]]

    The wrapped expressions that should be examined

  3. abstract val childParts: Seq[PartMeta[_]]

    The wrapped partitioning that should be examined

  5. abstract val childScans: Seq[ScanMeta[_]]

    The wrapped scans that should be examined

  6. abstract def convertToGpu(): OUTPUT

  7. abstract def tagSelfForGpu(): Unit

    Do any extra checks and tag yourself if you are compatible or not.

    Do any extra checks and tag yourself if you are compatible or not. Be aware that this may already have been marked as incompatible for a number of reasons.

    All of your children should have already been tagged so if there are situations where you may need to disqualify your children for various reasons you may do it here too.

    Keep this on the CPU, but possibly convert its children under it to run on the GPU if enabled.

    Keep this on the CPU, but possibly convert its children under it to run on the GPU if enabled. By default this just returns what is wrapped by this. For some types of operators/stages, like SparkPlan, each part of the query can be converted independent of other parts. As such in a subclass this should be overridden to do the correct thing.

    Returns the list of reasons the entire plan can't be replaced.

    Returns the list of reasons the entire plan can't be replaced. An empty set means the entire plan is ok to be replaced, do the normal checking per exec and children.

  22. final def entirePlanWillNotWork(because: String): Unit

    Call this if there is a condition found that the entire plan is not allowed to run on the GPU.
