Say I have a sinatra route ala:

put '/data' do
  request.body.read
  [...]
end

It appears that the entire request.body is read into memory. Is there a way to consume the body as it comes into the system, rather than having it all buffered in Rack/sinatra beforehand?

I see I can do this to read the body in parts, but the entire body still seems to be read into memory beforehand.

put '/data' do
  while request.body.read(1024) != nil 
    [...]
  end
  [...]
end
