Review comment:
       I agree. The only thing I am afraid is if at any point we are taking 
again the checkpoint config from the `env` and we disregard what the 
`StreamGraphGenerator` has set. From a quick look, it does not seem to be the 
case, so I pushed another commit with the change. Please have a look and let me 
know what you think.
