-----------------------------------------
[~zhuzh]
I think you are right it raises a lot of questions and would need more time to
understand.
Now I tend to agree with the previous suggestion to expose method for
{{Transformation}}/{{StreamNode}} to set weights for managed memory. We should
just carefully handle the case of already set known spec and then trying to set
the weight for managed memory. I think we should not allow mixing weight and
known spec.
If we decide to add WeightedResourceSpec later we can adjust the weight setting
methods accordingly.

>
> To calculate managed memory fraction for an operator with UNKNOWN resources,
> we need to know whether the operator will use managed memory, according to
> FLINK-14062.
> To achieve this, we need an interface to set/get whether an operator uses
> managed memory. It can be part of {{ResourceSpec}} or directly locates in the
> operator description classes ({{Transformation}}/{{StreamNode}}).
