TRTH - direct copy from one AWS S3 bucket to another S3 bucket
@Christiaan Meihsl - I have seen your documentation on downloading directly from your AWS S3 bucket at https://developers.thomsonreuters.com/article/boost-trth-downloads-aws
I am wondering if it possible to go one step further and issue a direct S3 to S3 copy command. Such commands are normally much faster because the client does not actually download the data, it is copied by AWS on their back-end. See for example: https://docs.aws.amazon.com/AmazonS3/latest/dev/CopyingObjectUsingJava.html
Do you have any advice on how to authenticate the copy with AWS?

Answering my own question: As far as I can tell, this is not currently possible. DSS would have to provide a signed URL authorizing this request.
When downloading TRTH data from AWS, you get the pre-signed URL. The question could be how to copy an object from the pre-signed URL. I found a few answers via the stack overflow.
Someone has mentioned about a pre-signed PUT URL with the x-amz-copy-source header.
Thanks - but I think the accepted answer (that it is not possible) is probably correct. I don't see a way you can use the signature when the query has to change from a download to a copy. The signature is made of a hash that includes the request parameters, any change would invalidate the signature.
