Reference documentation and code samples for the Google Cloud Data Loss Prevention v2 API class PrivacyMetric.Types.KMapEstimationConfig.Types.AuxiliaryTable.
An auxiliary table contains statistical information on the relative
frequency of different quasi-identifiers values. It has one or several
quasi-identifiers columns, and one column that indicates the relative
frequency of each quasi-identifier tuple.
If a tuple is present in the data but not in the auxiliary table, the
corresponding relative frequency is assumed to be zero (and thus, the
tuple is highly reidentifiable).
