Question: Modifying Checkpoint Interval at runtime

[Morgan Geldenhuys]

I am working with the Flink at the moment and am interested in modifying 
the codebase so that the checkpoint interval can be changed at runtime, 
(e.g. if it was set to kickoff the distributed snapshot process every 10 
seconds, and then I wanted to change it to every 15 seconds instead 
without restarting). I was wondering, in your professional opinion, is 
this possible? Of course I am not expecting this to be a simple 
implementation, however, what considerations would I need to take into 
account and which parts of the codebase would this modification involve.
