Task scheduling method, device, equipment and system and storage medium

Abstract

The embodiment of the invention discloses a task scheduling method, device, equipment and system and a storage medium. The method comprises the steps: acquiring the maximum serial number in occupied scheduling serial numbers corresponding to a current scheduling event from a storage service, wherein the occupied scheduling serial numbers are sequentially increased; sending an occupation request ofa first serial number to the storage service, and when an occupation success message returned by the storage service is received, setting the first serial number as a first scheduling serial number corresponding to the first scheduler, the first serial number being the next serial number of the maximum serial number, and allocating a corresponding task based on the first scheduling serial number.According to the technical scheme provided by the embodiment of the invention, the occupied scheduling sequence number is stored by adopting the lightweight storage service, the scheduler autonomously applies for the scheduling sequence number and allocates the corresponding task according to the applied scheduling sequence number, so that the service resources are saved, and the maintenance costcaused by additional components is avoided.

Description

Technical field[0001]The embodiments of the present invention relate to the field of computer technology, in particular to task scheduling methods, devices, equipment, systems, and storage media.Background technique[0002]At present, task scheduling problems are often involved in the construction of distributed software systems. Task scheduling is generally implemented by a scheduler. In a distributed system, there are usually multiple schedulers.[0003]Common scheduler implementations are generally through third-party scheduling services to schedule services in the system, but a third-party scheduler system framework needs to be introduced, and other middleware, such as zookeeper, must be prepared around the framework. In this mode, a coordinator needs to be used to manage multiple schedulers, which is highly dependent on third-party scheduling components, wastes service resources, and additional components will also bring additional maintenance costs. Therefore, the current task sch...

In this mode, a coordinator needs to be used to manage multiple schedulers, which is highly dependent on third-party scheduling components, wasting service resources, and additional components will also bring additional maintenance costs

Therefore, the current task scheduling scheme is still not perfect and needs to be improved
