Method, system and device for updating source information based on time wheel and a storage medium

Abstract

The invention provides a method, a system, and a device for updating goods source information based on a time wheel, and a storage medium. The method comprises the following steps: obtaining goods source information and an update cycle of each goods source information; setting multi-stage time wheels, wherein each stage time wheel is divided into end-to-end cell queues according to respective unittime values, and the unit time value of the subsequent stage time wheel is equal to the total time value of the adjacent preceding stage time wheels; Each level of time wheel is provided with a cyclepointer, and the cycle pointer of each level of time wheel moves one cell forward every other unit time value; adding an update event of the source information to a cell of a matching time wheel; andperforming an update event of the cell to which the loop pointer of the time wheel with the smallest unit time value currently points. The invention adopts a multi-stage time wheel to realize that asmall amount of storage space stores a large amount of update events; Only part of the tasks are handled at a time, which reduces unnecessary computations and saves system resources.

Description

technical field [0001] The invention relates to the technical field of logistics, in particular to a method, system, device and storage medium for updating source information based on a time wheel. Background technique [0002] After the source of goods is released, until the source of goods becomes invalid, it is necessary to automatically update the source of goods on a regular basis, so that users can check the latest and effective source of goods at any time. [0003] The traditional solution will add a scheduled task to the system for each supply source, and the scheduled task will be automatically triggered at the target time point to update the supply source. This solution will generate a large number of scheduled tasks in the system. The scheduled tasks consume a lot of resources, and the system cannot support a large number of scheduled tasks at the same time. [0004] It should be noted that the information disclosed in the above background technology section is o...
