How can you handle large responses in a chunked/streaming fashion? You can return a StreamBody with an InputStream. That works fine if you are serving a file, but what if you are generating a large response chunk by chunk? And don't want to buffer the whole response before start serving the first part.

Your InputStream can be any kind of InputStream, including one that computes its bytes on demand

[mbonnin]

It's just an abstraction, the implementation and buffering is up to you

[Mikael Ståldal]

Yes, I guess so. However, in this case it would be more convenient to be able to push data to the response, rather than having the response pulling data from me.

[mbonnin]

TCP has Flow control, you can't push faster than the client can accept

[mbonnin]

If you want to push, you have to buffer

[Mikael Ståldal]

Yeah, I guess some kind of reactive stream with back-pressure would be nice here.
