Zhu Zhu created FLINK-14566: ------------------------------- 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. cc [~ykt836] [~trohrmann] [~wuzang] [~azagrebin] -- This message was sent by Atlassian Jira (v8.3.4#803005)
