SamplingTransformer

class SamplingTransformer extends Model[SamplingTransformer] with SamplerParams

Data transformer which takes sample of the data. Resulting dataframe is constructed in a way that results are non-determenistic and might vary from run to run (unless the seed is specified or with replacement enabled - in these cases we fallback to default data set sampling which is determenistic).
