    o

    Object that contains message ksb.csle.common.proto.StreamOperatorProto.SampleSimpleRandomInfo SampleSimpleRandomInfo contains attributes as follows:

    • fractions: map of specific the sampling rate (required) If the fraction value is 1, the result dataframe is same as the original dataframe.
    • withReplacement: Parameter to specify whether to sample with or without replacement (required) If withReplacement is false, the result dataframe does not have the same rows.
    • seed: Local random seed (optional)

    message SampleSimpleRandomInfo {
    required double fraction = 3;
    required bool withReplacement = 4 [default = false];
    optional int64 seed = 5;
