Abstract

The embodiment of the invention relates to the technical field of task processing, and discloses a delay task processing method and device, and equipment. The method comprises the steps of setting a task loading thread and a task execution thread; inserting the delay task into a database, wherein the database stores the task content and the execution time of the delay task; in the task loading thread, loading N delay tasks needing to be executed within the future time t1 into a memory ordered queue, and updating the next execution time of the delay tasks loaded into the memory ordered queue tobe second execution time, wherein the second execution time is equal to the sum of the execution time and t2, and t2 is larger than t1; and in the task execution thread, sequentially obtaining delaytasks according to the arrangement sequence of the delay tasks in the memory ordered queue, executing the delay tasks according to the execution time of the delay tasks, and deleting the delay tasks in the database after the delay tasks are successfully executed. By means of the mode, the memory consumption is reduced, and transverse expansion is facilitated.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of task processing, and in particular to a delayed task processing method, device and equipment. Background technique [0002] At present, electronic devices such as computers or mobile terminals need to process a large number of tasks, including real-time tasks and delayed tasks. Delayed tasks mean that in business logic processing, some logic needs to be delayed, such as closing the live broadcast room over time, automatically canceling orders over time, sending SMS over time, etc. The tasks set for the above logic are delay tasks. [0003] In the prior art, most implementation schemes for delayed tasks are generally realized by using Redis sorted set or local time wheel algorithm. However, these methods consume a lot of memory when there are many tasks. Contents of the invention [0004] In view of the above problems, embodiments of the present invention provide a delayed tas...
