Scheduling method and system of flow computing system

The embodiment of the invention discloses a scheduling method and system of a flow computing system. The flow computing system comprises a plurality of working nodes. The method comprises the following steps: determining a target working node; obtaining a local operation graph reflecting the related local operation process of the target working node; updating the local operation graph based on scheduling information, the scheduling information including addition or deletion of work nodes and/or change of a local operation process; generating first control information based on the updated localoperation diagram; and sending the first control information to a working node involved in the updated local operation graph, so that the working node involved in the updated local operation graph modifies upstream and/or downstream working node information based on the first control information, thereby finishing scheduling. Therefore, the flow computing system has an efficient stream operationscheduling method, and the
