Streaming with gunicorn

Question

I'm trying to stream data from a flask/gunicorn server:

while (True):
    result = json.dumps(tweetQueue.get())
    yield result

However, 30 seconds into the stream, gunicorn times out my connection and stops the stream. How can I make the timeout such that publishing new data to the stream from the server will restart the timeout so the stream will not be terminated?

Thanks!

I am answering my own question after doing some more research.

gunicorn server:app -k gevent

This uses asynchronous workers, which have the benefit of using Connection: keep-alive when serving requests. This allows the request to be served indefinitely.
