Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/) that was published on June 30, 2025.

COPY has many parameters that can be used in many situations. However, not all parameters are supported in each situation. For example, to load from ORC or PARQUET files there is a limited number of supported parameters. For more information, see [COPY from columnar data formats](copy-usage_notes-copy-from-columnar.md).
