Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025.
If you would like to use Python UDFs, create the UDFs prior to that date.
Existing Python UDFs will continue to function as normal. For more information, see the
blog post
Query processing
Amazon Redshift routes a submitted SQL query through the parser and optimizer to develop a query plan. The execution engine then translates the query plan into code and sends that code to the compute nodes for execution.
