Storage class should expose head operation & range requests

[marksteele]

Is your feature request related to a problem? Please describe.

I would like to be able to perform a HEAD operation on an object stored in S3 (ex: so that I can determine the file size) as well as the ability to perform range requests (to read specific byte ranges out of a file). In my case, to retrieve just a few bytes at the end of a file.

Describe the solution you'd like

• A head operation in the Storage API that would return the headers of the request as a map.
• The ability to provide byte offsets to the get call (to generate properly signed urls)

Describe alternatives you've considered

Possibly expose the raw S3 client and utility functions to get key prefixes for logged in user, etc... That would allow for these types of advanced use-cases to be implemented.

I'd like to see this also. Possibly relates to #5044

I am also waiting for this functionality. Ability to get file last modified attribute is much needed to see if file changed.
In my use case, I want to download only if file changes. Is this possible with amplfiy?

Now we can access properties of file using Storage.getProperties . Please do find the Reference Doc
