Amazon’s S3 service continues to evolve, making it an even more robust and user-friendly cloud storage platform. In its latest update, Amazon has enhanced the S3 LIST API, providing users with the ability to track the restore status of objects stored in Amazon S3 Glacier Flexible Retrieval and Amazon S3 Glacier Deep Archive. This added functionality lets users easily determine if an object has been restored and is ready for use.
This modification to the S3 LIST API can easily be incorporated into users’ applications, and allows users to effortlessly identify and access objects they’ve restored from S3 Glacier. Amazon Athena has already incorporated this feature, so users can conduct queries against data that’s been restored from cost-effective S3 Glacier storage classes.
Using this new feature is straightforward. When using the S3 LIST API, include the optional header ‘”x-amz-optional-object-attributes: RestoreStatus”. In the S3 LIST response, you’ll find the restore status of any ongoing or recently restored object. It will either indicate “‘in progress” or “complete”. If the restore process has been completed, the response will also display the expiration date that was specified in your original restore request.
This innovative feature is available in all commercial AWS regions, including the AWS GovCloud (U.S.) regions, and the AWS China regions (Beijing, operated by Sinnet, and Ningxia, operated by NWCD).
To retrieve the S3 Glacier restore status of objects, you can use the AWS SDK, API, or CLI with the S3 List API. For additional details about the S3 LIST API, the Amazon documentation provides an extensive overview. By leveraging these tools, you can optimize your cloud storage usage, ensuring that your data is ready when you need it.
