Distributed timed task control device and method

Abstract

The invention provides a distributed timed task control device. The distributed timed task control device comprises a receiving module, a database module, a plurality of scheduling modules and an execution module, wherein the receiving module is used for receiving instructions of timed task Cron; the database module is used for storing Cron records, and every Cron record is provided with corresponding current state information; the plurality of scheduling modules are used for scheduling the Cron records in the database module respectively according to a scheduling timetable and placing the Cron records in an execution queue according to the current state information corresponding to the Cron records when the Cron records meet the scheduling timetable; and the execution module is used for executing the Cron records in the execution queue. The distributed timed task control device can be used for processing high-concurrency Cron tasks and is only related to users, the users can use a uniform resource locator (URL) outside an application program to serve as an address of timed tasks, and the distributed timed task control device is flexible and convenient. The invention further provides a distributed timed task control method.

Description

technical field [0001] The invention relates to the technical field of cloud development, in particular to a distributed timing task control device and method. Background technique [0002] Cron, a scheduled task, is a task that executes planned work at an agreed time. For example, it can be stipulated in the configuration file that the httpd server will be restarted at 4 o'clock every morning, and a letter will be sent to a mailbox at 10 o'clock every night, which are all scheduled tasks. [0003] In Linux systems, scheduled tasks are generally undertaken by cron, and cron can execute specific tasks according to the time agreed in the configuration file. Set cron to start automatically at boot time. After cron starts, it will read all its configuration files, such as the global configuration file / etc / crontab, and each user's scheduled task configuration file, and then cron will call the work task on time according to the command and execution time. [0004] Cron can run...

AI Technical Summary

Problems solved by technology

[0004] Cron can run jobs without manual intervention, but the disadvantage is that it does not provide any form of API. Cron tasks can only be configured through the application configuration file, which is limited to the internal use of the application and lacks flexibility.
