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. 

# ODBC driver options
<a name="configure-odbc-options"></a>

You can use configuration options to control the behavior of the Amazon Redshift ODBC driver.

In Microsoft Windows, you typically set driver options when you configure a data source name (DSN). You can also set driver options in the connection string when you connect programmatically, or by adding or changing registry keys in `HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\{{your_DSN}}`. For more information about configuring a DSN, see [Using an Amazon Redshift ODBC driver on Microsoft Windows](install-odbc-driver-windows.md).

In macOS X, you set driver configuration options in your `odbc.ini` and `amazon.redshiftodbc.ini` files, as described in [Use an ODBC driver manager to configure the driverUse an ODBC driver manager to configure the driver](odbc-driver-configure-mac.md). Configuration options set in an `amazon.redshiftodbc.ini` file apply to all connections. In contrast, configuration options set in an `odbc.ini` file are specific to a connection. Configuration options set in `odbc.ini` take precedence over configuration options set in `amazon.redshiftodbc.ini`.

For information about how to set up ODBC driver configuration options, see the [Amazon Redshift ODBC connector installation and configuration guide](https://s3.amazonaws.com/redshift-downloads/drivers/odbc/1.6.3.1008/Amazon+Redshift+ODBC+Connector+Install+Guide.pdf).
