Review Comment:
This sounds like a separate PR.
I think it is only beneficial if the downstream processing logic can keep up
with the increased IO rate. That said I think it probably is the common case
for reading from S3/GCS. I don't know what `OpenInputStream` in the filesystem
interface is used for so I can't comment.
