Title: DATA DISTRIBUTION POLICY ADJUSTMENT METHOD, DEVICE AND SYSTEM
Abstract:
Disclosed are a data distribution policy adjustment method, device and system, which belong to the field of data processing. The method is used for processing data of a stream processing service in a stream processing system and comprises: acquiring, by a control device, a resource usage report of each working device; according to the resource usage report of each working device and a pre-set policy, determining a processing unit adjustment policy, the processing unit adjustment policy comprising increasing the number of post processing units or reducing the number of post processing units; selecting at least one working device from the at least one working device as an executor of the processing unit adjustment policy; and generating an adjustment instruction comprising the processing unit adjustment policy, and sending the adjustment instruction to the determined working device. In the process of conducting a stream processing service, the number of post processing units required to be adjusted is determined by a control device according to the resource usage reports of various working devices, thereby avoiding the defect that the number of post processing units cannot be changed.
