Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0020] In the embodiment of the present invention, the logical clock is used as the unit, and according to the load condition of the distributed system in the previous logical clock cycle, the number of background tasks in the current logical clock cycle is generated, and the background task is scheduled based on the distributed system load with the logical clock as the cycle. .

[0021] The distributed system in the embodiment of the present invention may be a distributed file storage system or a distributed object storage system (such as of 9000 series), it can also be a distributed block storage system (such as of series), etc., may also be a distributed system in a public cloud, or other distributed computing systems. by of series. Exemplary as figure 1 As shown, the distributed block storage system includes multi...

Abstract

A Task Scheduling Scheme, Quotas for background tasks are generated based on logical clocks and load indices of the distributed system, Quotas are allocated to multiple business nodes for processing,so as to realize flexible scheduling of background tasks based on distributed system load in logical clock cycle, improve the flexibility and real-time of background task scheduling, and ensure the accuracy of background task scheduling.

Description

technical field [0001] The present invention relates to the field of information technology, and more specifically, to a task scheduling method, device and computer program product. Background technique [0002] In the public cloud, the foreground business, which is closely related to user operation delay, only needs to complete the relatively simple marking operation to return the operation result to the client, and then the background task processes all the data at regular intervals. For example, if a user deletes a folder with 1 million files, after the client selects the folder and clicks delete, after the server of the public cloud receives the batch delete request, the foreground business only needs to store this file in the cache or database. After the folder is marked with a deletion tag, a response message that the deletion operation has been successful can be returned to the user. This business processing only involves one cache or database read and write operatio...
