[jira] [Updated] (FLINK-21916) Allow OPERATOR and PYTHON
ManagedMemoryUseCase to be used in the same operator
[ https://issues.apache.org/jira/browse/FLINK-21916?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dian Fu updated FLINK-21916:
----------------------------
Summary: Allow OPERATOR and PYTHON ManagedMemoryUseCase to be used in the same operator (was: Allows multiple kinds of ManagedMemoryUseCase for the same operator)
> Allow OPERATOR and PYTHON ManagedMemoryUseCase to be used in the same operator

> Currently, the implementation of [SimpleTransformationTranslator|https://github.com/apache/flink/blob/97bfd049951f8d52a2e0aed14265074c4255ead0/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/graph/SimpleTransformationTranslator.java#L119] restricts that OPERATOR and PYTHON use case could not be used in the same operator. For batch mode of Python DataStream API:
> - OPERATOR use case will be added firstly in BatchExecutionUtils.applyBatchExecutionSettings for a keyed operator during translation
> - Then the PYTHON use case which is set in the transformation could not be added in [SimpleTransformationTranslator|https://github.com/apache/flink/blob/97bfd049951f8d52a2e0aed14265074c4255ead0/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/graph/SimpleTransformationTranslator.java#L119] as the streamNode.getManagedMemoryOperatorScopeUseCaseWeights() is not empty.
> We need to remove the restriction in [SimpleTransformationTranslator|https://github.com/apache/flink/blob/97bfd049951f8d52a2e0aed14265074c4255ead0/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/graph/SimpleTransformationTranslator.java#L119] if there are no special reasons.
