Answer

1. Create a text file to record properties called athena.properties.
2. Save the file to the My Tableau Repository\Datasources directory.
3. Add a key-value pair:
   •  S3OutputEncOption=<Option Name> where <Option Name> is the encryption protocol to be used. For example, for server-side encryption with an Amazon S3-managed key, the key-value pair would be S3OutputEncOption=SSE_S3
4. If the value used for Step 3 is SSE_KMS or CSE_KMS, add another key-value pair to set the S3OutputEncKMSKey property of the KMS key ARN or ID to use for encrypting data.
5. Save the file.
