Heroku, I stream you!

• Rack

  A modular Ruby web server interface.

  

Rails seems to have streaming functionality to handle this kind of output generation in the ActionController::Live. Also in Rails edge (future v7) there is a #send_stream method that seems to achieve this functionality so I copied it to my Rails 5.2 app into a controller concern and changed the CSV generation logic to implement the Enumerable #each method. It was not working until I also override the Last-Modified header. See this issue discussion.
