StatSampleBy

final class StatSampleBy extends GeneratedMessageV3 with StatSampleByOrBuilder

Returns a stratified sample without replacement based on the fraction
given on each stratum.
It will invoke 'Dataset.stat.freqItems' (same as 'StatFunctions.freqItems')
to compute the results.

Protobuf type spark.connect.StatSampleBy
