Amplify-js: More efficient way to get file's metadata for list of files than Storage.list() -> Storage.get({download:true})?

[sandeshakya]

I have an application that lists the files uploaded by a user. I'm using Storage.list() for this. I would like to use each file's metadata (x-amz-meta-owner) to enable/disable a button. For now, I'm using Storage.get() with download:true to get the metadata, (I've added x-amz-meta-owner in the CORS configuration). I've found this to be slow and expensive, as it has to download each file as a UIntArray. Is there a more efficient way to get the metadata for each file than this?

Thank you.

@sandeshakya interesting request. Can you go deeper into your use case and what you're trying to build so that we can look at this further from a feature perspective?

[sandeshakya]

@undefobj for my use case, I want to set the disabled attribute based on a metadata attribute for a file. But for a more general case, an option to return the objects' metadata might also help in filtering, using metadata to conditionally render certain objects, without having to download every object in a folder.

So this is specifically for LIST operations?

[sandeshakya]

@powerful23 , that's the kind of functionality I was hoping could be added to Amplify. Good find. Thank you.

@undefobj , might make more sense to have it in the Get operation, similar to @powerful23's post.
