tDQRules / tDataQualityRules

Validates data using data quality rules by connecting Talend Studio to Qlik Talend Data Integration, or to a Talend app.

Information noteAttention: From Talend Studio 8.0 R2025-06, the tDataQualityRules Standard component is replaced by tDQRules. This component lets you use the rules from:
  • Qlik Talend Data Integration.
  • Talend Cloud Data Inventory.
  • Talend Cloud Data Stewardship.
  • The hybrid version of Talend Data Stewardship 8.0 R2022-07 and greater.

For Apache Spark Jobs, you can only use tDataQualityRules with the Talend apps.

For more information on each app, see the corresponding documentation:

A data quality rule is a set of business requirements which defines the values your data must comply with.

To retrieve the data quality rules into a JAR file, tDQRules connects Talend Studio to one of the app listed above. Talend Studio uses the retrieved library so you can apply data quality rules to your data. For more information on how the component works with Talend apps, see Description of the local and Cloud/hybrid process.

The following table describes the categories and subcategories into which the component returns the data:

Output categories tDataQualityRules tDQRules
Valid

These data follow the Main flow.
  • Valid: The data fulfill the condition and the validation expression or the data fulfill the alternative validation expression only.
  • Not applicable (NA): The data do not fulfill the condition. The rule cannot be applied to the data.
 The data fulfill the condition and the validation expression or the data fulfill the alternative validation expression only.
Invalid

These data follow the Reject flow.
  • Invalid: The data fulfill the condition but not the validation expression.
  • Not executable (NE): The rule cannot be executed on the data. For example, when the data types do not match.
  • Invalid: The data fulfill the condition but not the validation expression.
  • Not executable (NE): The rule cannot be executed on the data. For example, when the data types do not match.
  • When there is no result, it means there is no result to return

.
Not Applicable

These data follow the Not_Applicable flow.

 Not applicable to this component The data do not fulfill the condition. The rule cannot be applied to the data.

This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.

You need the Qlik Talend Cloud Enterprise Edition to use the tDQRules / tDataQualityRules component.

Apache Spark tDataQualityRules supports:
  • In local mode, Apache Spark 3.0 and greater.
  • Cloudera Data Engineering service with Apache Spark 3.1 or 3.2.

Standard properties

These properties are used to configure tDQRules and tDataQualityRules running in the standard Job framework.

The standard tDQRules and tDataQualityRules components belong to the Data Quality family.

Information noteImportant:

If you are using tDataQualityRules, see Basic settings for tDataQualityRules . This component has been combined with tDQRules from Talend Studio 8.0 R2025-06 but the properties of tDataQualityRules are the same. They do not depend on the version you are using.

Basic settings for tDQRules

Properties Description
Cloud Select the app from which you want to retrieve the rules:
  • Qlik Talend Cloud Data Integration
  • Talend Cloud Data Inventory or Stewardship

Click Apply to enable more settings.

If you selected Talend Cloud Data Inventory or Stewardship, you are using tDataQualityRules, see Basic settings for tDataQualityRules .

Property Type

Select the way the file path and the schema will be set.

  • Built-In: The file path and the schema will be set locally for this component.

  • Repository: The file details stored centrally in Repository > Metadata will be reused by this component.

    You need to click the [...] button next to it and in the pop-up Repository Content dialog box, select the file to be reused, and all related properties will be automatically filled in.
Schema and Edit schema

A schema is a row description that defines the number of fields (columns) to be processed and passed on to the next component.

Click Sync columns to retrieve the schema from the previous component connected in the Job.

Select the Schema type:

  • Built-In: You create and store the schema locally for this component only.

  • Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

View schema: choose this option to view the schema only.

Change to built-in property: choose this option to change the schema to Built-in for local changes.

Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion.

The supported types are: Boolean, Date, Double, Dynamic, Float, Integer, Long, Short, and String.
URL
Information noteImportant: You need the Rules - View permission to retrieve the rules.

Enter the URL of the app. For example, https://qcs.us.qlikcloud.com/.
API key Enter your API key. To generate one, see Generating an API key.
Rule library timestamp After you entered the URL and token, click Fetch rules.

If the URL and token are correct, the rules are retrieved into Talend Studio: yyyy-MM-dd hh:mm:ss (library_number).

When you click Fetch rules, a JAR file containing the rule definition is created in:
studio-path\configuration\.m2\repository\org\talend\libraries\rule-number

When you update the rules in the app, click Fetch rules to retrieve the latest version.
Rule name

Select the rule from the list and click Refresh table.
Rule content

Associate the variables of the rule with the input data.

The rule is retrieved from the library:
  • Rule variable: The variable from the Cloud app.
  • Input column: The input column from Talend Studio.
  • Fact column: The input column from Talend Studio when the column is dynamic.
When no rules or input columns are available, verify that:
  • Rules have been retrieved in Rule library timestamp.
  • The input schema is correct.
