For streaming using HTTPoison I wrote an article few weeks ago: Download Large Files with HTTPoison Async Requests, but it would be better to use directly a library like ExAws.S3. I can’t find a function to get an Elixir stream from an S3 object though…
Update
Am I wrong or here in the ExAws.S3 there is a massive overhead: https://github.com/ex-aws/ex_aws_s3/blob/master/lib/ex_aws/s3/download.ex#L76 ??
Each chunk seems to be requested with a separate http request…
