The RandomURL transformer is designed to populate specified database columns with random URL (Uniform Resource Locator) addresses. This tool is highly beneficial for simulating web content, testing applications that require URL input, or anonymizing real web addresses in datasets.


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 -


Utilizing advanced algorithms or libraries for generating URL strings, the RandomURL transformer injects random, plausible URLs into the designated database column. Each generated URL is structured to include the protocol (e. g., "http://", "https://"), domain name, and path, offering a realistic range of web addresses for various applications.

Example: Populate random URLs for the webpages table

This example illustrates how to configure the RandomURL transformer to populate the page_url column in a webpages table with random URLs, providing a broad spectrum of web addresses for testing or data simulation purposes.

RandomURL transformer example
- schema: "public"
  name: "webpages"
    - name: "RandomURL"
        column: "page_url"
        keep_null: false

With this configuration, the page_url column will be filled with random URLs for each entry, replacing any existing non-NULL values. Setting the keep_null parameter to true allows for the preservation of existing NULL values within the column, accommodating scenarios where URL data may be intentionally omitted.
