Description

• Added a new data source, aws_cloudfront_key_value_store, to retrieve attributes of a CloudFront Key Value Store, such as its ARN.

  • When using aws_cloudfrontkeyvaluestore_key, the ARN of the Key Value Store must be specified. This new data source makes it easier to work with an existing Key Value Store.

Closes #42530
