GpuWindowIterator

class GpuWindowIterator extends Iterator[ColumnarBatch] with BasicWindowCalc

An Iterator that performs window operations on the input data. It is required that the input data is batched so all of the data for a given key is in the same batch. The input data must also be sorted by both partition by keys and order by keys.

  24. def computeBasicWindow(cb: ColumnarBatch): Array[ColumnVector]

    Compute the basic aggregations.

    Compute the basic aggregations. In some cases the resulting columns may not be the expected types. This could be caused by cudf type differences and can be fixed by calling castResultsIfNeeded or it could be different because the window operations know about a post processing step that needs to happen prior to castResultsIfNeeded.

    cb

    the batch to do window aggregations on.

    returns

    the cudf columns that are the results of doing the aggregations.
