Problems solved by technology

[0004] 1. It cannot well support scheduling requirements in complex scenarios, such as cross-job flow dependencies, event triggers, etc.;
[0005] 2. It cannot directly support the multi-tenant environment, and scheduling bottlenecks often occur when the scheduling level reaches millions or even tens of millions;
[0006] 3. The management support for scheduling resources is weak

Abstract

The invention discloses a job scheduling method and a system, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: analyzing a receivedtrigger event into input conditions of jobs, and putting the jobs into a job set after all the input conditions of the jobs are ready; taking out to-be-distributed jobs from the job set and distributing the jobs; and obtaining job instance information from the distributed job queue and executing jobs. According to the method, common polling in the scheduling process can be avoided, and the scheduling performance is greatly improved; the whole job scheduling adopts a decentralized design and is executed by a plurality of independent components in series, and the components are clear in division of labor and are decoupled from one another through message queues, so that system expansion can be performed by simply adding examples.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a job scheduling method and system. Background technique [0002] Job scheduling in a multi-tenant environment faces the following challenges: 1. With the increase of tenants, the number of daily running tasks can reach more than one million, and due to different business fields, there are complex relationships among jobs. Dependency, different jobs have different running frequency requirements, and even time zone differences; 2. Heterogeneous and diverse computing platforms (such as Hadoop platform, stream computing platform, massively parallel processing MPP platform, etc.), Heterogeneous platforms determine the complexity of scheduling job types, including script jobs such as Shell and Python, big data tasks such as Spark and Hive, and container tasks under the microservice framework; 3. Complex resource management, multiple In a tenant environment, it is necessary ...
