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 system, and relates to the technical field of computers. A specific implementation of the method includes: parsing the received trigger event into the input conditions of the job, and putting the job into the job set after all the input conditions of the job are ready; taking out the job to be dispatched from the job set and performing the job Dispatch; obtain job instance information from the dispatched job queue and execute the job. This implementation can avoid the common polling in the scheduling process and greatly improve the scheduling performance; the entire job scheduling is a "decentralized" design, which is executed by multiple individual components in series. The queue is decoupled, so that the system can be expanded by simply adding instances.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method and system for job scheduling. 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 tasks between 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. Third, complex resource management, many In a tenant environment, it is necessa...
