class GpuRunningWindowIterator extends Iterator[ColumnarBatch] with BasicWindowCalc

An iterator that can do row based aggregations on running window queries (Unbounded preceding to current row) if and only if the aggregations are instances of GpuBatchedRunningWindowFunction which can fix up the window output when an aggregation is only partly done in one batch of data. Because of this there is no requirement about how the input data is batched, but it must be sorted by both partitioning and ordering.

  25. 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.
