Abstract: Systems and methods for data sharing include generating at least one sharing plan with a cheapest cost and/or a shortest execution time for one or more sharing arrangements. Admissibility of the one or more sharing arrangements is determined such that a critical time path of the at least one sharing plan does not exceed a staleness level and a cost of the at least one sharing plan does not exceed a capacity. Sharing plans of admissible sharing arrangements are executed while maintaining the staleness level.
