Dividing a stream computing application graph of a service for scheduling and processing

Abstract

A service scheduling method, applied to a stream computing system, is presented. The stream computing system includes a master control node and multiple working nodes, and the master control node is configured to schedule sub-services included in the service to the multiple working nodes for processing. The method includes acquiring a stream computing application graph of the service; dividing the stream computing application graph according to operator degrees and operator potentials of operators in the stream computing application graph and according to a division quantity for dividing the stream computing application graph, to obtain divided sub-graphs with the division quantity; and scheduling a sub-service corresponding to an operator included in each divided sub-graph to a working node corresponding to the divided sub-graph for processing. The method provided in embodiments of the present disclosure can enable services to use physical resources and network resources in a balanced manner.
