Instance Attribute Details

#check_expression ⇒ String

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.

end

#column_selectors ⇒ Array<Types::ColumnSelector>

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.

Returns:

• (Array<Types::ColumnSelector>)

end

#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.

Returns:

• (Boolean)

  SENSITIVE = []
  include Aws::Structure
end

#name ⇒ String

The name of the rule.

Returns:

• (String)

# File 'gems/aws-sdk-gluedatabrew/lib/aws-sdk-gluedatabrew/types.rb', line 3278

class Rule < Struct.new(
  :name,
  :disabled,
  :check_expression,
  :substitution_map,
  :threshold,
  :column_selectors)
  SENSITIVE = []
  include Aws::Structure
end

#substitution_map ⇒ Hash<String,String>

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`".

Returns:

• (Hash<String,String>)

# File 'gems/aws-sdk-gluedatabrew/lib/aws-sdk-gluedatabrew/types.rb', line 3278

class Rule < Struct.new(
  :name,
  :disabled,
  :check_expression,
  :substitution_map,
  :threshold,
  :column_selectors)
  SENSITIVE = []
  include Aws::Structure
end

#threshold ⇒ Types::Threshold

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.

Returns:

• (Types::Threshold)
