    Public API of SlidingWindowJoin.

    Public API of SlidingWindowJoin. Perform sliding window join/aggregation on a label dataset and a list of fact datasets which share the same join key. Callers need to invoke this API multiple times if the label dataset need to be joined with fact datasets on multiple join keys.

    labelDataset

    Label dataset as a LabelData

    factDatasets

    List of fact datasets as FactData to join on label dataset

    returns

    The result of the sliding window join/aggregation as a DataFrame
