RandomCurrency

The RandomCurrency transformer is tailored to populate specified database columns with random currency codes. This tool is highly beneficial for applications involving the simulation of international financial data, testing currency conversion features, or anonymizing currency information 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

Utilizing a comprehensive list of global currency codes (e.g., USD, EUR, JPY), the RandomCurrency transformer injects random currency codes into the designated database column. This feature allows for the creation of diverse and realistic financial transaction datasets by simulating a variety of currencies without relying on actual financial data.

Example: Populate random currency codes for the transactions table

This example outlines configuring the RandomCurrency transformer to populate the currency_code column in a transactions table with random currency codes. It is an effective way to simulate international transactions across multiple currencies.

RandomCurrency transformer example

- schema: "public"
  name: "transactions"
  transformers:
    - name: "RandomCurrency"
      params:
        column: "currency_code"
        keep_null: false

In this configuration, the currency_code column will be updated with random currency codes for each 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 currency data may not be applicable.
