partitionBy(f: (T) ⇒ Boolean): (DataSet[T], DataSet[T])
Splits a DataSet into two parts based on the given filter function.
Splits a DataSet into two parts based on the given filter function. Note, that filtering is done twice on the same data twice, thus, caching beforehand is recommended!
- f
the boolean filter function
- returns
two DataSets
