zhuzhurk opened a new pull request #10427: [FLINK-14566] Enable to get/set whether an operator uses managed memory
URL: https://github.com/apache/flink/pull/10427
 
 
   ## What is the purpose of the change
   
   To calculate managed memory fraction for an operator with UNKNOWN resources, we need to know whether the operator will use managed memory to better utilize memory memory for better performance, according to FLINK-14062.
   
   To achieve this, we need an interface to set/get whether an operator uses managed memory.
   
   ## Brief change log
   
     - *Enable to get/set managed memory weight in Transformation*
     - *Set Transformation managed memory weight to corresponding StreamNode*
     - *Adjust managed memory fraction calculation regarding managed memory weights*
   
   ## Verifying this change
   
   This change added tests and can be verified as follows:
   
     - *Added unit tests for changes in Transformation*
     - *Added unit tests for changes in StreamGraph/StreamNode*
     - *Adjusted unit tests for managed memory fraction calculation changes*
