---------------------------------------

The simple solution to define a weight on {{Transformation/StreamNode}} sounds good to me. [~zhuzh] let me know once you have the PR ready. I can help with the review.

> 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}}).
