Abstract

The invention discloses a method, system and device for optimally executing an expected timed task and a storage medium, and the method comprises the steps: responding to a received asynchronous task, and judging whether the asynchronous task is the expected timed task or not; in response to the asynchronous task being an expected timed task, judging whether a first difference value between an execution moment of the expected timed task and a current moment exceeds preset time or not; in response to the situation that a first difference value between the execution moment of the expected timed task and the current moment exceeds the preset time, storing the ID and parameter information of the expected timed task into Redis, and setting a key as an exclusive mark of the expected timed task; and calculating a second difference value between the first difference value and the preset time, and setting the timeout time of the key as a third difference value between the second difference value and a preset value. According to the method, on the basis of a release and subscription mode of a key space message of Redis, an asynchronous task calling module is redefined, and an expected timed task execution module of Celery is optimized.

Description

technical field [0001] The present invention relates to the field of task processing, and more specifically, to a method, system, computer equipment and readable medium for optimally executing expected timing tasks. Background technique [0002] Celery is an asynchronous task scheduling tool that adopts the distributed task queue mode and supports high-concurrency execution of massive tasks. Celery's architecture consists of passive middleware (usually Redis or RabbitMQ), task execution unit (worker process) and task execution result storage ( Storage database) consists of three parts, which are mostly used to perform asynchronous or timing tasks, such as: server memory, CPU, Memory usage data collection, or asynchronously initiate to execute a command to a designated server and other scenarios. [0003] In the prior art, Celery executes the ETA task asynchronously, mainly through the apply_async function that comes with Celery, using the specified parameter eta (the value i...
