Abstract

The invention discloses a delay task performance method and device and relates to the technical field of a computer. One embodiment of the method comprises the steps of extracting all tasks in a window from the special window in a queue according to a preset time period with duration of T, wherein the window of which tasks are extracted is determined through the time of extracting the tasks, when the tasks are added, the window for adding the tasks in the queue is determined according to the current time of adding the tasks, thereby adding the tasks to the window, the window for adding the tasks and the determined window of which tasks are extracted in the time period after preset delay duration KT are the same window, and the K is a positive integer; and performing the extracted tasks. According to the embodiment of the invention, distributed delay processing can be supported, and when the performance of the plurality of tasks is delayed, excessive threads do not need to be started, so the system stability is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for delaying task execution. Background technique [0002] At present, when it is necessary to delay the execution of the task, the usual method is to implement it by calling the Thread.sleep() function of java. The Thread.sleep() function will suspend the thread executing the task for a period of time. After the time is over, the thread will be woken up, so as to realize the delayed execution of the task. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: first, the method of calling Thread.sleep () function, the delay processing of the task and the execution of the task are carried out by the same device, if When the device has a problem, or restarts, or redeploys, all tasks on the device will be lost, and the delay information of the corresponding tasks will also...
