Flink Jira Bot reassigned FLINK-5105: ------------------------------------- Assignee: (was: Fabian Hueske) > Improve ReduceState: value put into ReducingState should always be a copy > ------------------------------------------------------------------------- > > Key: FLINK-5105 > URL: https://issues.apache.org/jira/browse/FLINK-5105 > Project: Flink > Issue Type: Improvement > Components: Runtime / State Backends > Reporter: sunjincheng > Priority: Major > Labels: auto-unassigned > > In case of overlapping sliding windows, multiple references are hold on the > same object. If we modify value1 or value2 the results are incorrect. The > value that is put into a ReducingState is always copied. That would allow to > modify and emit one of the two input values (the one which is comes from the > state). > The FoldingState has the same problem. -- This message was sent by Atlassian Jira (v8.3.4#803005)
