Yes, that’s possible. I’m only on mobile now for the next few hours so pardon the brevity. There is a test which does exactly that - stream from AWS and then back to AWS. I’d suggest take a look at that if you can - and I’ll revert here again when I’m properly back online.
Edit: the test is here: image/test/stream_image_test.exs at main · elixir-image/image · GitHub
