Myasuka commented on issue #7009: [FLINK-10712] Support to restore state when using RestartPipelinedRegionStrategy URL: https://github.com/apache/flink/pull/7009#issuecomment-453846070 @StefanRRichter It seems union operator state, somehow, conflicts with partial recovery. However, since `region` means the minimal pipeline connected sub graph, why it could have union-state across different regions? Otherwise, we might need to introduce some limitations in this scenario. Would you please kindly help to clarify more clearly on this corner case?
