↳ non_null_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\NonNullExpectation Row-level rule which evaluates whether each column value is null.
↳ set_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\SetExpectation Row-level rule which evaluates whether each column value is contained by a specified set.
↳ regex_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\RegexExpectation Row-level rule which evaluates whether each column value matches a specified regex.
↳ uniqueness_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\UniquenessExpectation Row-level rule which evaluates whether each column value is unique.
↳ statistic_range_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\StatisticRangeExpectation Aggregate rule which evaluates whether the column aggregate statistic lies between a specified range.
↳ row_condition_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\RowConditionExpectation Row-level rule which evaluates whether each row in a table passes the specified condition.
↳ table_condition_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\TableConditionExpectation Aggregate rule which evaluates whether the provided expression is true for a table.
↳ sql_assertion	Google\Cloud\Dataplex\V1\DataQualityRule\SqlAssertion Aggregate rule which evaluates the number of rows returned for the provided statement.
↳ column	string Optional. The unnested column which this rule is evaluated against.
↳ ignore_null	bool Optional. Rows with null values will automatically fail a rule, unless ignore_null is true. In that case, such null rows are trivially considered passing. This field is only valid for the following type of rules: * RangeExpectation * RegexExpectation * SetExpectation * UniquenessExpectation
↳ dimension	string Required. The dimension a rule belongs to. Results are also aggregated at the dimension level. Supported dimensions are ["COMPLETENESS", "ACCURACY", "CONSISTENCY", "VALIDITY", "UNIQUENESS", "INTEGRITY"]
↳ threshold	float Optional. The minimum ratio of passing_rows / total_rows required to pass this rule, with a range of [0.0, 1.0]. 0 indicates default value (i.e. 1.0). This field is only valid for row-level type rules.
↳ name	string Optional. A mutable name for the rule. * The name must contain only letters (a-z, A-Z), numbers (0-9), or hyphens (-). * The maximum length is 63 characters. * Must start with a letter. * Must end with a number or a letter.
