If you have user-defined functions (UDFs) configured in your application, you can reuse the transformation logic from these UDFs in INFACore.
You can leverage mapplets from you your Informatica Intelligent Cloud Services organization as UDFs in INFACore. Get the list of configured UDFs from your organization and use these UDFs in INFACore and transform the data.
You can also chain UDFs to generate a data pipeline dynamically and run the pipeline. To chain the UDFs, set the UDF cascade_fields source attribute to True for a data pipeline in the Python SDK.
