> logic is quite clever. It downloads the next couple parts in parallel using
> range requests, and then buffers them in memory in order to reorder them and
> expose a single contiguous stream. I translated the logic to Java and
> modified the S3AFileSystem to do similar things, and am able to achieve
> 150MB/s download speeds as well. It is mostly done but I have some things to
> clean up first. The PR is here:
> https://github.com/palantir/hadoop/pull/47/files
> It would be great to get some other eyes on it to see what we need to do to
> get it merged.
