Abstract

The embodiment of the invention provides a timed task execution method, device and system based on a time window. At least one worker periodically executes tasks in parallel at a specified scheduling interval, wherein the process that each worker schedules and executes the tasks each time comprises the steps: firstly, setting the corresponding time window, querying a task table according to the corresponding time window, and acquiring timing tasks from the task table to serve as respective corresponding preparation tasks; each worker executes a respective corresponding preparation task, and modifies the task state of the corresponding preparation task in the task table to execution completion. By means of the scheme, the single-point problem in a timed task system is solved, and the effects of achieving thermal disaster recovery and automatically recovering timed tasks without manual intervention are achieved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a time window-based timing task execution method, device and system. Background technique [0002] Timed tasks are often used in software development. For example, the ERP system regularly sends emails at 6:00 p.m. every day to remind people to clock in after get off work; in the settlement system, it regularly checks the payment status of orders, cancels orders that are not paid after timeout, and releases commodity resources. At present, many companies use Linux timing task scripts to implement timing task technology. The advantage of this is simplicity and fast development. Especially those who use PHP language to develop the system, the language itself is a scripting language, it is easy to use the operating system to complete the scheduled task function without additional development. The biggest problem with the existing technology is that there is a single point in the system, ...
