Overtime task scheduling system and method

Abstract

The invention discloses an overtime task scheduling system and method. Among them, the system includes: the scheduling engine provides overtime task registration service; according to the registration information or the end polling notification message returned by any overtime task executor, the overtime task is distributed to the corresponding overtime task executor or callback notification service is provided by using a preset algorithm ;The timeout task executor polls the timeout task at the time granularity of the timeout task executor according to the timeout task distributed by the scheduling engine, and returns a polling notification message to the scheduling engine after the polling ends, and polls at an irregular time interval The overtime task not only ensures the timeliness of the overtime task, can be called in time, but also saves system resources, overcomes the problem of serious timeout of the overtime task due to the time interval setting is too large when polling according to a fixed time interval, and If the time interval is set too small, the polling will be too frequent, which will cause waste of system resources and other problems.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an overtime task scheduling system and method. Background technique [0002] In the current marketing activities, there are many tasks that need to be triggered according to the specified time in the future, for example, the start time of the activity and the end time of the activity. For such tasks, a timeout task needs to be registered, and the corresponding business operation of the task will be called back after the timeout. [0003] At present, the timeout task scheduling mainly includes: the timer class that comes with JDK based on memory implementation; the timeout class based on database implementation. However, no matter whether it is memory implementation or persistence implementation, timeout tasks need to be polled. In general, Polling is performed at fixed time intervals. However, it is unreasonable to set the polling time interval too large or too small. If the...

[0003] At present, the timeout task scheduling mainly includes: the timer class that comes with JDK based on memory implementation; the timeout class based on database implementation. However, no matter whether it is memory implementation or persistence implementation, timeout tasks need to be polled. In general, Polling is performed at fixed time intervals. However, it is unreasonable to set the polling time interval too large or too small. If the time interval is set too large, the timeout task will time out seriously. If the time interval is set too small, the polling will be too short. Frequent, a waste of system resources, in addition, if it is a persistent timeout task, it will also increase the pressure on the database
