  11. def columnarEvalToColumn(expr: Expression, batch: ColumnarBatch): GpuColumnVector

    Tries to resolve a GpuColumnVector by evaluating an expression over a batch.

    Tries to resolve a GpuColumnVector by evaluating an expression over a batch.

    This is a common handling of a GpuExpression for the nodes asking for a single GpuColumnVector.

    expr

    the input expression to be evaluated.

    batch

    the input batch.

    returns

    a GpuColumnVector if it succeeds. Users should close the column vector to avoid memory leak.

  23. def resolveColumnVector(any: Any, numRows: Int): GpuColumnVector

    Tries to resolve a GpuColumnVector from a Scala Any.

    Tries to resolve a GpuColumnVector from a Scala Any.

    This is a common handling of the result from the columnarEval, allowing one of

    • A GpuColumnVector
    • A GpuScalar For other types, it will blow up.

    It is recommended to return only a GpuScalar or a GpuColumnVector from a GPU expression's columnarEval, to keep the result handling simple. Besides, GpuScalar can be created from a cudf Scalar or a Scala value, So the 'GpuScalar' and 'GpuColumnVector' should cover all the cases for GPU pipelines.

    any

    the input value. It will be closed if it is a closeable after the call done.

    numRows

    the expected row number of the output column, used when 'any' is a GpuScalar.

    returns

    a GpuColumnVector if it succeeds. Users should close the column vector to avoid memory leak.
