Python language support for UDFs - Amazon Redshift
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Python language support for UDFs

You can create a custom UDF based on the Python programming language. The Python 2.7 standard library is available for use in UDFs, with the exception of the following modules:

  • ScrolledText

  • Tix

  • Tkinter

  • tk

  • turtle

  • smtpd

In addition to the Python Standard Library, the following modules are part of the Amazon Redshift implementation:

You can also import your own custom Python modules and make them available for use in UDFs by executing a CREATE LIBRARY command. For more information, see Example: Importing custom Python library modules.

Important

Amazon Redshift blocks all network access and write access to the file system through UDFs.

Note

Python 3 isn’t available for Python UDFs. To get Python 3 support for Amazon Redshift UDFs, use Scalar Lambda UDFs instead.
