Description

Retrieves detailed information about the ruleset.

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-ruleset
--name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--name (string)

The name of the ruleset to be described.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Output

Name -> (string)

The name of the ruleset.

Description -> (string)

The description of the ruleset.

TargetArn -> (string)

The Amazon Resource Name (ARN) of a resource (dataset) that the ruleset is associated with.

Rules -> (list)

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

(structure)

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

Name -> (string)

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)

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 -> (map)

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`".

key -> (string)

value -> (string)

Threshold -> (structure)

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 -> (double)

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.

(structure)

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.

CreateDate -> (timestamp)

The date and time that the ruleset was created.

CreatedBy -> (string)

The Amazon Resource Name (ARN) of the user who created the ruleset.

LastModifiedBy -> (string)

The Amazon Resource Name (ARN) of the user who last modified the ruleset.

LastModifiedDate -> (timestamp)

The modification date and time of the ruleset.

ResourceArn -> (string)

The Amazon Resource Name (ARN) for the ruleset.

Tags -> (map)

Metadata tags that have been applied to the ruleset.

key -> (string)

value -> (string)
