摘要：
Total global minimum costs can be determined for multiple sub-plans for completing a multi-operation database process to be performed in a distributed database management system that includes a plurality of nodes. The multiple sub-plans can include different distributions of node locations of a plurality of operators among the plurality of nodes. An optimal plan having a lowest total minimum global cost can be selected from the multiple sub-plans.
