Thediff()function is useful for analyzing the rate of change or identifying trends within a dataset. By default, thediff()function computes differences between adjacent elements. However, you can specify a different period using theperiodsparameter to compute differences at different intervals. ...
This adds a diff transformation to Dataset and DataFrame that computes the differences between two datasets / dataframes, i.e. which rows of one dataset / dataframes to add, delete or change to get to the other dataset / dataframes.
def of[T](left: Dataset[T], right: Dataset[T], idColumns: Seq[String], ignoreColumns: Seq[String] = Seq.empty): DataFrame = default.diff(left, right, idColumns, ignoreColumns) /** * Returns a new DataFrame that contains the differences between the two Datasets * of the same type ...
