Abstract

The invention discloses a task processing method and device, computer equipment and a storage medium, and the method can comprise the steps: obtaining a task description file for any task, wherein thetask description file comprises the parameters of an operator and the data transmission relation between operators; constructing a directed acyclic graph according to the data transfer relationship;and creating and executing each operator based on the parameters of the operator according to the sequence specified in the directed acyclic graph. By applying the scheme of the invention, the flexibility of task processing and the like can be improved.

Description

【Technical field】 [0001] The invention relates to computer application technology, in particular to a task processing method, device, computer equipment and storage medium. 【Background technique】 [0002] In practical applications, task processing can be implemented based on a directed acyclic graph (DAG, Directed Acyclic Graph). DAG graph is a kind of directed graph, which is characterized by no cycle in the graph, and is often used to represent the driver dependencies between events and manage the scheduling between tasks. The task may be an Extract-Transform-Load (ETL, Extract-Transform-Load) task or the like. [0003] However, the current task implementation is too customized, that is, special business processing logic needs to be implemented for different tasks, the implementation method is not flexible enough, and the implementation complexity is increased. 【Content of invention】 [0004] In view of this, the present invention provides a task processing method, dev...
