-------------------------------
Summary: Enable ResourceSpec to get/set whether managed memory is
used
Key: FLINK-14566
URL: https://issues.apache.org/jira/browse/FLINK-14566
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Affects Versions: 1.10.0
Reporter: Zhu Zhu
Fix For: 1.10.0
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.
- onHeapManagedMemory==MemorySize.ZERO means on heap managed memory is used,
while onHeapManagedMemory==null means not.
- similar for off heap managed memory.
getters: isUsingManagedMemoryOnHeap()/isUsingManagedMemoryOffHeap()
setters:
setUsingManagedMemoryOnHeap(boolean)/setUsingManagedMemoryOffHeap(boolean)
(setters are only allowed to invoke on UNKNOWN)
{{ResourceSpec#isKnown()}} should be added to replace existing UNKNOWN usages
for equality checking.
