Managed Keyed state update

[Alexey Trenikhun]

Let’s say I have Managed Keyed state - MapState<String,Tuple2<String,String>> 
x, I initialize for state for “k0” - x.put(“k0”, new Tuple2<>(“a”, “b”));
Later  I retried state Tuple2<String,String> v = x.get(“k0”); and change value: 
v.f0=“U”;, does it make state ‘dirty’? In other words, do I need to call 
x.put(“k0”, v) again or change will be saved by checkpoint anyway because value 
was changed?
