Aspects of the disclosure relate to evaluating the rollout of a change to a data processing framework (DPF). A first set of jobs is selected out of a plurality of jobs. The first set of jobs is processed by the DPF with the proposed change enabled and the other jobs of the plurality of jobs by the DPF without the change enabled. A performance cost value is determined for each of the jobs in the first set of jobs processed by the DPF with the proposed change enabled and for each of the other jobs of the plurality of jobs processed by the DPF with the proposed change disabled. Based on the performance cost values of the jobs in the first set of jobs and the performance cost values of the other jobs of the plurality of jobs, a determination is made whether the proposed change is beneficial to the DPF.
