Description

Asynchronous distribution task data chain management method and system
Technical Field

Background
In the prior art, the application which is generally constructed can encounter unpredictable situations such as slow response speed of dependent service, a small amount of requests and large consumption of CPU and memory resources, or sudden traffic peaks, and the like, so that the response of an application system is slow. In order to increase the response speed of the application and to cost less, computing resources are generally reserved in advance, but these resources are idle for most of the time, which undoubtedly increases the cost; it is relatively better to decouple the logic consuming a lot of resources from the main program, and the logic is asynchronously executed by the elastically extensible system, which not only can increase the response speed, but also can save the cost.
In the process of uploading the video or the picture, the process of generating the compressed video or the thumbnail can be asynchronously processed when the video or the picture is successfully uploaded, but if the asynchronous process of generating the compressed video or the thumbnail fails, the page cannot look up the uploaded video or the picture; or when the offline large file is acquired, the processing process of the large file is time-consuming, the processing process is stripped off and is executed asynchronously, and the file content still cannot be effectively acquired due to failure in the processing process of the large file executed asynchronously.
Therefore, the existing asynchronous task processing method strips logic with long time delay and large resource consumption from the main program, reduces service time delay, improves user experience, and is executed asynchronously by an elastically extensible system, so that resources are allocated reasonably, and cost is reduced. However, in the existing asynchronous branch task execution process, although the client can collect the task execution state, the client cannot effectively master the whole flow condition of the asynchronous branch task execution, and under different service scenes, the asynchronous service processing result difference greatly affects complex factors, so that the difficulty is increased for subsequent effective processing.
