Delay task processing method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a delay task processing method and device, electronic equipment and a storage medium. The method comprises the following steps: performing heap sorting on each to-be-executed delay task according to task execution time to construct a task small top heap; according to the task execution time of the to-be-executed delay task corresponding to a heap top element in the task small top heap, determining trigger control information of task polling; and according to the trigger control information of the task polling, triggering the polling to determine a target delay task from the to-be-executed delay tasks so as to carry out delay task processing. By adopting the scheme, the delay task needing to be executed recently can be quickly found by using the quick reconstruction capability of the small top heap for the delay task, the trigger control information of the task polling is determined according to the delay task needing to be executed recently, subsequent task polling only needs to be executed according to the trigger control information, frequent polling is not needed, occupation of a CPU and a disk is reduced, and resource consumption of empty polling is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular, to a delayed task processing method, device, electronic equipment, and storage medium. Background technique [0002] In the trading platform, it is often necessary to use delayed tasks to realize the functions of automatically canceling the order if the payment is not made at the point, and automatically processing the after-sales service if the delivery is not delivered after timeout. [0003] In the related technology, it is usually to add the delayed task to the message queue, and trigger the execution of the task according to the scheduled scan of the message queue, but each delayed task needs to be bound with configuration parameters such as the corresponding queue name, expiration time attribute, and routing key. It will increase the amount of code and the memory overhead of message middleware; at the same time, the implementation of delayed ...

[0003] In the related technology, it is usually to add the delayed task to the message queue, and trigger the execution of the task according to the scheduled scan of the message queue, but each delayed task needs to be bound with configuration parameters such as the corresponding queue name, expiration time attribute, and routing key. It will increase the amount of code and the memory overhead of message middleware; at the same time, the implementation of delayed tasks is usually done by polling and scanning tasks every few seconds. waste of
