Hi! Yes, Golden Retriever is intended to handle this, and unfortunately it doesn’t support large files yet 
We’ve been meaning to do it since landing Golden Retriever almost two years ago: https://github.com/transloadit/uppy/issues/257 but priorities have been hard.
I’m setting a post-1.0 release Slack reminder for us to actually examine what we neeed to do to implement this, because it’s been a very vague todo thus far which has made it hard to start on. We’ll know more in 3 weeks
