Task allocation method and device, electronic equipment and computer readable medium

Abstract

The invention provides a task allocation method and device, electronic equipment and a computer readable medium, and relates to the technical field of data processing. The method comprises the following steps: receiving a task allocation request sent by one of a plurality of equipment nodes in a task cluster; allocating the new task to a preset number of virtual nodes according to the task allocation request; and allocating the to-be-allocated tasks on the virtual nodes to the equipment nodes bound with the virtual nodes. According to the embodiment of the invention, afte the new task is obtained, firstly, tasks are allocated to a preset number of virtual nodes; the tasks on the virtual nodes are distributed to the corresponding equipment nodes; in each task allocation, the allocation modedoes not need to be readjusted according to the number of nodes, it is guaranteed that the tasks can be obtained by a certain involved node in the cluster and scheduled and executed according to setexecution time, failure processing work is well done when the nodes fail, and it is guaranteed that the tasks cannot be lost due to node failures.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular, the present disclosure relates to a task allocation method, device, electronic equipment, and computer-readable medium. Background technique [0002] A scheduled task is a task that needs to be executed according to a set time, such as a mobile phone alarm clock is a typical scheduled task. The classification of timing tasks can be generally divided into two types: stand-alone timing tasks and distributed timing tasks. [0003] In the prior art, for distributed timing tasks, its solutions mainly include time-sharing scheme, high availability scheme, multi-channel heartbeat scheme, task preemption scheme and task polling scheme, as well as a stand-alone version of Quartz ( Quatz formula) framework, but the stand-alone version has problems such as single point of failure, limited execution scale, etc., coupled with the gradual increase of distributed scenarios, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of this disclosure is to at least solve one of the above-mentioned technical defects, especially when processing tasks in the prior art, there are problems such as single point of failure and limited execution scale, while each node in distributed Quartz will be preempted A large number of threads wait for database locks, resulting in a technical problem of waste of resources
