User Defined Functions let a BigQuery user do data transformations on query results. If you are using BigQuery for ELT, then UDFs let you do the Transform step entirely in BigQuery, using javascript functions on a per-row basis.
This pull request allows an Airflow DAG to pass a UDF config to the BigQuery operator, and have that UDF config be included in the query API call.
See https://cloud.google.com/bigquery/user-defined-functions for more details on UDFs.
