How do I find if all the S3 objects are restored - amazon-web-services

Question

I recently have restored S3 Deep Archive objects using Python.
There are over a million of them and I need to make it sure clearly.
If possible, I would like to use python to check if all objects have been restored.
Can someone please advice me how to do this?
Thank you

Answer 1

From restore_object() documentation:
To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response.
And under head_object():
If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:
x-amz-restore: ongoing-request="false", expiry-date="Fri, 21 Dec 2012 00:00:00 GMT"

Although not Python, here is the logic to perform this use case using AWS SDK for Java v2.
package com.example.s3;
import software.amazon.awssdk.auth.credentials.ProfileCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3Client;
import software.amazon.awssdk.services.s3.model.HeadObjectRequest;
import software.amazon.awssdk.services.s3.model.HeadObjectResponse;
import software.amazon.awssdk.services.s3.model.S3Exception;
public class GetObjectRestoreStatus {
public static void main(String[] args) {
final String usage = "\n" +
"Usage:\n" +
" <bucketName> <keyName> \n\n" +
"Where:\n" +
" bucketName - The Amazon S3 bucket name. \n\n"+
" keyName - A key name that represents the object. \n\n";
if (args.length != 2) {
System.out.println(usage);
System.exit(1);
}
String bucketName = args[0];
String keyName = args[1];
ProfileCredentialsProvider credentialsProvider = ProfileCredentialsProvider.create();
Region region = Region.US_EAST_1;
S3Client s3 = S3Client.builder()
.region(region)
.credentialsProvider(credentialsProvider)
.build();
checkStatus(s3,bucketName,keyName);
s3.close();
}
// snippet-start:[s3.java2.getrestorestatus.main]
public static void checkStatus(S3Client s3, String bucketName, String keyName) {
try {
HeadObjectRequest headObjectRequest = HeadObjectRequest.builder()
.bucket(bucketName)
.key(keyName)
.build();
HeadObjectResponse response = s3.headObject(headObjectRequest);
System.out.println("The Amazon S3 object restoration status is "+response.restore());
} catch (S3Exception e) {
System.err.println(e.awsErrorDetails().errorMessage());
System.exit(1);
}
}
// snippet-end:[s3.java2.getrestorestatus.main]
}
