Konstantin Knauf updated FLINK-6220: ------------------------------------ Labels: (was: auto-closed) Priority: Not a Priority (was: Minor) > Fine-grained copy-on-write for Heap(Map/List)States in CopyOnWriteStateTable > ---------------------------------------------------------------------------- > > Key: FLINK-6220 > URL: https://issues.apache.org/jira/browse/FLINK-6220 > Project: Flink > Issue Type: Improvement > Components: Runtime / State Backends > Affects Versions: 1.3.0 > Reporter: Stefan Richter > Priority: Not a Priority > > Currently, the copy-on-write mechanism in {{CopyOnWriteStateTable}} uses > serializers to create copies of state objects. In case of > {{Heap(Map/List)State}}, those state objects are collections, and a deep > copy-on-write is performed on those collections as a whole. We can > investigate ways to track changes on a more fine grained level, for example > deep copy only individual entries in the lists or maps. -- This message was sent by Atlassian Jira (v8.3.4#803005)
