Fan Hong created FLINK-32810: -------------------------------- Summary: Improve managed memory usage in ListStateWithCache Key: FLINK-32810 URL: https://issues.apache.org/jira/browse/FLINK-32810 Project: Flink Issue Type: Improvement Components: Library / Machine Learning Reporter: Fan Hong
Right now, by default, `ListStateWithCache` will use up all the managed memory allocated for`ManagedMemoryUseCase.OPERATOR`. It could bring some bugs in some situations. For example, there exist more than one `ListStateWithCache`s in a single operator, or there are other places using managed memory of `ManagedMemoryUseCase.OPERATOR`. An approach to resolve such cases is to let the developer of the operator be aware about the usage of managed memory of `ManagedMemoryUseCase.OPERATOR`, instead of implicitly use up all of it. Therefore, I think it is better to add a parameters `fraction` to specify how much memory is used in the `ListStateWithCache`. -- This message was sent by Atlassian Jira (v8.20.10#820010)
