The RandomFirstName transformer is designed to populate specified database columns with random first names. This tool is indispensable for applications requiring the simulation of user profiles, testing user registration systems, or anonymizing user data 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 -


The RandomFirstName transformer utilizes a comprehensive list of first names to inject random first names into the designated database column. This feature allows for the creation of diverse and realistic user profiles by simulating a variety of first names without using real user data.

Example: Populate random first names for the user_profiles table

This example demonstrates configuring the RandomFirstName transformer to populate the first_name column in the user_profiles table with random first names. It is an effective method for simulating a variety of user profiles with diverse first names.

RandomFirstName transformer example
- schema: "public"
  name: "user_profiles"
    - name: "RandomFirstName"
        column: "first_name"
        keep_null: false

In this configuration, the first_name column will be updated with random first names for each user profile entry, replacing any existing non-NULL values. If the keep_null parameter is set to true, existing NULL values in the column will be preserved, ensuring the integrity of records where first name information is not applicable or provided.
