Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, 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/). 

# Declining a datashare from a different AWS account in Amazon Redshift
<a name="writes-declining-datashare"></a>

With Amazon Redshift, you can decline datashares shared by other AWS accounts, enabling seamless and secure data sharing across organizational boundaries. Datashares are shareable database objects that encapsulate data from one or more Amazon Redshift databases. 

As a consumer administrator, you can reject any datashare whose state is available or active. After you reject a datashare, consumer cluster users lose access to the datashare. Amazon Redshift doesn't return the rejected datashare if you call the `DescribeDataSharesForConsumer` API operation. If the producer administrator runs the `DescribeDataSharesForProducer` API operation, they will see that the datashare was rejected. Once a datashare is rejected, the producer administrator can authorize the datashare to a consumer cluster again, and the consumer administrator can choose to associate their AWS account with the datashare or reject it. 

If your AWS account has an association to a datashare and a pending association to a datashare that's managed by Lake Formation, rejecting the datashare association that's managed by Lake Formation also rejects the original datashare. To reject a specific association, the producer administrator can remove authorization from a specified datashare. This action doesn't affect other datashares.

To reject a datashare, use the AWS console, the API operation `RejectDataShare`, or `reject-datashare` in the AWS CLI.

------
#### [ Console ]

To reject a datashare using the AWS console, perform the following steps.

1. Sign in to the AWS Management Console and open the Amazon Redshift console at [https://console.aws.amazon.com/redshiftv2/](https://console.aws.amazon.com/redshiftv2/).

1. In the navigation menu, choose **Datashares**.

1. Choose **From other accounts**.

1. In the **Datashares from other accounts** section, choose the datashare you want to decline. When the **Decline datashare** page appears, choose **Decline**.

After you decline the datashares, you can't revert the change. Amazon Redshift removes the datashares from the list. To see the datashare again, the producer administrator must authorize it again.

------
#### [ CLI ]

To reject a datashare, the administrator uses the following command: 

```
reject-data-share
--data-share-arn <value>
```

For more information about the command, see [reject-data-share](https://docs.aws.amazon.com/cli/latest/reference/redshift/reject-data-share.html).
