Zhu Zhu updated FLINK-14566:
----------------------------
Description:
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}}).

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.
-I'd propose to define special values of
onHeapManagedMemory/offHeapManagedMemory
in ResourceSpec(introduced in- FLINK-14405) -to distinguish whether managed
memory is used.-
-For UNKNOWN resource spec, onHeapManagedMemory==MemorySize.ZERO means on heap
managed memory is used, while onHeapManagedMemory==null means not. For
non-UNKNOWN resource spec, managed memory size larger than zero indicates it is
used.-
-similar for off heap managed memory.-
-getters: isUsingManagedMemoryOnHeap()/isUsingManagedMemoryOffHeap()-
-setters:
setUsingManagedMemoryOnHeap(boolean)/setUsingManagedMemoryOffHeap(boolean)-
-(setters are only allowed to invoke on UNKNOWN, should be ignored for
non-UNKNOWN for compatibility)-
-{{ResourceSpec#isKnown()}} should be added to replace existing UNKNOWN usages
for equality checking.-
