> The sync gunicorn worker class is not production ready unless behind a proxy like nginx. This is clearly documented in the gunicorn docs, but never mentioned anywhere in the Airflow docs. I feel that either the default should be changed to one of the asynchronous models or users should be adequately warned.
> What makes this even more painful is that AWS ELB tries to keep open the connections for health checks, essentially DOSing the Airflow webserver if used with the default config. But it happens with Chrome's URL preloading as well as mentioned in the link below.
