I agree, we would need some FLIPs to cover this. Actually there is already some work on this topic initiated by Matthias Pohl (ccd). Please see this: https://cwiki.apache.org/confluence/display/FLINK/FLIP-360%3A+Merging+the+ExecutionGraphInfoStore+and+the+JobResultStore+into+a+single+component+CompletedJobStore
This FLIP actually covers some of these limitations already and other outstanding issues in the operator. Cheers, Gyula
