Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] figure 1 A schematic diagram of the architecture of a distributed scheduling system applying the embodiment of the present invention is shown. Such as figure 1 As shown, the distributed scheduling system architecture may include a task database 101 , a scheduling cluster 102 and a business cluster 103 . The communication between each cluster is based on a custom protocol or based on a TCP / IP network communication protocol. In the...

The embodiment of the invention relates to the task scheduling field, in particular to a task scheduling method and device. The task scheduling method and device are used for solving the problem of inaccuracy of the task generation moment in the prior art. According to the embodiment, a scheduling node acquires a current record corresponding to a to-be-processed task in a task database; the current record comprises a task generation identifier and an optimistic lock version number; when the scheduling node determines that the task generation identifier is consistent with a local task generation identifier locally stored in the scheduling node, the optimistic lock version number and the task generation identifier are updated; the scheduling node sends an update message to the task database,wherein the update message comprises the updated optimistic lock version number and the updated task generation identifier; the update message is used for making the task database determine whether to update the current record; the scheduling node receives an update response sent by the task database; and whether the to-be-processed task is triggered is determined according to the update response. Through the task scheduling method and device, the problems of inaccuracy of the task generation moment and task missing in the prior art can be avoided.
Description
technical field [0001] The embodiments of the present invention relate to the field of task scheduling, and in particular, to a task scheduling method and device. Background technique [0002] At present, there are often many tasks that need to be processed regularly. For example, the task of generating weekly reports needs to be executed once a week, the task of sending emails needs to be executed once every day at 3:00 am, the task of analyzing logs needs to be executed once every day at 1:00 am, and the task of cleaning logs needs to be executed every day at 12:00 am Once; the task of information collection needs to be performed every two hours, etc. [0003] These tasks have something in common: they need to be executed periodically. For such tasks that need to be periodically and regularly executed, there are generally two commonly used methods in the prior art. The first way is to generate the next task one cycle after the completion of the scheduling node generatio...
