Extracts a random sample data from a big data set.

tReservoirSampling extracts a sample from the input data set in such a way that profiling results on the sample data are uniform and homogeneous with the profiling results on the full data set.

In local mode, Apache Spark 2.4.0 and later versions are supported.
