Parameters
  • Name (string) --

    [REQUIRED]

    The name of the ruleset to be updated.

  • Description (string) -- The description of the ruleset.
  • Rules (list) --

    [REQUIRED]

    A list of rules that are defined with the ruleset. A rule includes one or more checks to be validated on a DataBrew dataset.

    • (dict) --

      Represents a single data quality requirement that should be validated in the scope of this dataset.

      • Name (string) -- [REQUIRED]

        The name of the rule.

      • Disabled (boolean) --

        A value that specifies whether the rule is disabled. Once a rule is disabled, a profile job will not validate it during a job run. Default value is false.

      • CheckExpression (string) -- [REQUIRED]

        The expression which includes column references, condition names followed by variable references, possibly grouped and combined with other conditions. For example, (:col1 starts_with :prefix1 or :col1 starts_with :prefix2) and (:col1 ends_with :suffix1 or :col1 ends_with :suffix2) . Column and value references are substitution variables that should start with the ':' symbol. Depending on the context, substitution variables' values can be either an actual value or a column name. These values are defined in the SubstitutionMap. If a CheckExpression starts with a column reference, then ColumnSelectors in the rule should be null. If ColumnSelectors has been defined, then there should be no column reference in the left side of a condition, for example, is_between :val1 and :val2 .

        For more information, see Available checks

      • SubstitutionMap (dict) --

        The map of substitution variable names to their values used in a check expression. Variable names should start with a ':' (colon). Variable values can either be actual values or column names. To differentiate between the two, column names should be enclosed in backticks, for example, ":col1": "`Column A`".

        • (string) --
          • (string) --
      • Threshold (dict) --

        The threshold used with a non-aggregate check expression. Non-aggregate check expressions will be applied to each row in a specific column, and the threshold will be used to determine whether the validation succeeds.

        • Value (float) -- [REQUIRED]

          The value of a threshold.

        • Type (string) --

          The type of a threshold. Used for comparison of an actual count of rows that satisfy the rule to the threshold value.

        • Unit (string) --

          Unit of threshold value. Can be either a COUNT or PERCENTAGE of the full sample size used for validation.

      • ColumnSelectors (list) --

        List of column selectors. Selectors can be used to select columns using a name or regular expression from the dataset. Rule will be applied to selected columns.

        • (dict) --

          Selector of a column from a dataset for profile job configuration. One selector includes either a column name or a regular expression.

          • Regex (string) --

            A regular expression for selecting a column from a dataset.

          • Name (string) --

            The name of a column from a dataset.
