class abacusai.api_class.feature_group.SamplingConfig

  Bases: `abacusai.api_class.abstract.ApiClass`

  An abstract class for the sampling config of a feature group

  __post_init__()

class abacusai.api_class.feature_group.NSamplingConfig

  Bases: `SamplingConfig`

  The number of distinct values of the key columns to include in the sample, or number of rows if key columns not specified.

  Parameters:

    - sampling_method (SamplingMethodType) – N_SAMPLING

    - sample_count (int) – The number of rows to include in the sample

    - key_columns (list[str]) – The feature(s) to use as the key(s) when sampling

  sample_count: int
  sampling_method: abacusai.api_class.enums.SamplingMethodType
  key_columns: List[str]
  __post_init__()

class abacusai.api_class.feature_group.PercentSamplingConfig

  Bases: `SamplingConfig`

  The fraction of distinct values of the feature group to include in the sample.

  Parameters:

    - sampling_method (SamplingMethodType) – PERCENT_SAMPLING

    - sample_percent (float) – The percentage of the rows to sample

    - key_columns (list[str]) – The feature(s) to use as the key(s) when sampling

  sample_percent: float
