Problems solved by technology

At present, the scheduling of tasks in distributed interactive data query systems based on query trees is mostly based on the heartbeat mechanism and task timeout mechanism for scheduling and distribution; the task scheduling and distribution method based on the heartbeat mechanism is easy for nodes whose heartbeat information fails to arrive in time. Misjudgment, the task scheduling and distribution method based on the task timeout mechanism cannot be reasonably processed for large-scale task queries

Abstract

The application discloses a task distribution method and device for a distribution server. The distribution server communicates with and is connected with terminal equipment and a processor server cluster; the method specifically comprises the following steps: receiving a task processing request sent by the terminal equipment, determining a to-be-processed task indicated by the task processing request; acquiring feature information of each processing server in the processing server cluster; determining an available processing server set in the processing server cluster and task load of each processing server in the processing server set according to the feature information; selecting the processing server from the available processing server set to be used as the target processing server;and distributing the to-be-processed task to the target processing server, thereby enabling the target processing server to process the to-be-processed task. Through the task distribution method disclosed by the application, the to-be-processed task is reasonably distributed and scheduled.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of data query, and in particular to a task distribution method, device and equipment for a distribution server. Background technique [0002] Data query system is an important tool for data analysis. With the advent of the era of big data, data query systems need to process more and more data. Among them, the distributed interactive data query based on the query tree is composed of a main server and many sub-servers. The main server is responsible for receiving requests, and through analysis and scheduling, decomposes a task into multiple sub-tasks, and then schedules these sub-tasks to be processed on different subservers. At present, the scheduling of tasks in distributed interactive data query systems based on query trees is mostly based on the heartbeat mechanism and task timeout mechanism for scheduling and distribution; the task scheduling and distri...
