RandomCCNumber

The RandomCCNumber transformer is specifically designed to populate specified database columns with random credit card numbers. This utility is crucial for applications that involve simulating financial data, testing payment systems, or anonymizing real credit card numbers in datasets.

Parameters

Name	Description	Default	Required	Supported DB types
column	The name of the column to be affected		Yes	text, varchar
keep_null	Indicates whether NULL values should be preserved	false	No	-

Description

By leveraging algorithms capable of generating plausible credit card numbers that adhere to standard credit card validation rules (such as the Luhn algorithm), the RandomCCNumber transformer injects random credit card numbers into the designated database column. This approach ensures the generation of credit card numbers that are realistic for testing and development purposes, without compromising real-world applicability and security.

Example: Populate random credit card numbers for the payment_information table

This example demonstrates configuring the RandomCCNumber transformer to populate the cc_number column in the payment_information table with random credit card numbers. It is an effective strategy for creating a realistic set of payment data for application testing or data anonymization.

RandomCCNumber transformer example

- schema: "public"
  name: "payment_information"
  transformers:
    - name: "RandomCCNumber"
      params:
        column: "cc_number"
        keep_null: false

With this setup, the cc_number column will be updated with random credit card numbers for each entry, replacing any existing non-NULL values. If the keep_null parameter is set to true, it will ensure that existing NULL values in the column are preserved, maintaining the integrity of records where credit card information is not applicable or available.
