An apparatus includes a processor to: receive a request to generate a superset job flow replacing multiple job flows including an output job flow and preceding job flows previously performed to generate an output data object; identify a first subset of mid-flow data object(s) generated by preceding job flow(s) as input(s) to the output job flow to generate the output data object; identify a second subset of the mid-flow data object(s) generated by preceding job flow(s) as input(s) to other preceding job flow(s) generating the first subset; in response to a lack of a second subset, derive the superset job flow and/or corresponding DAG to include at least one task of the output job flow and at least one task of each preceding job flow that generated the first subset; and transmit an indication of the generation of the superset job flow.
