Problems solved by technology

If a task flow adds a new downstream task with a high task level, and if the task level of the upstream task in the task flow is low, then it is likely that the upstream task cannot be executed as soon as possible due to insufficient resources. It also delays the execution of more important downstream tasks

Embodiment Construction

[0030] figure 1 Some tasks in the data warehouse are illustrated, and each box is a task, for example, the task may be a program for extracting a data set or a program for generating a report. in, figure 1 The direction of the arrows in represents the dependencies between the various tasks of the data warehouse. For example, an arrow direction is from task 1 to task 4, indicating that task 4 depends on task 1, and the output of task 1 will be used as the input of task 4. The dependency between tasks also represents the execution order between tasks. If task 4 depends on task 1, then task 1 is executed first, and then task 4 is executed. Task 1 can be called the upstream task of task 4. On the contrary, task 4 can be called the downstream task of task 1. A task can only start executing after all its upstream tasks have finished running. In many cases, a task may require multiple inputs, for example, figure 1 In the example shown in , both the output of task 1 and task 2 are ...

Abstract

The invention provides a task management method and apparatus. The method comprises the steps of comparing task levels of an upstream task and a downstream task in a task stream; and when the task level of the downstream task is higher than that of the upstream task, increasing the task level of the upstream task. According to the task management method and apparatus, the upstream task is executed more quickly, so that the downstream task can be executed as early as possible, and the delay influence of the upstream task on the downstream task is reduced.

Description

technical field [0001] The invention relates to computer technology, in particular to a task management method and device. Background technique [0002] With the rapid development of computer and network technology, people often use the network to deal with various types of affairs, such as online shopping, online payment, etc., and a large amount of data is generated in the process of using the network, such as commodity transaction data. It will be very important to find ways to organize and analyze these data to better assist business development. Data Warehouse (Data Warehouse) is a subject-oriented, integrated, and relatively stable data collection. The data warehouse can be used to uniformly process the independent and scattered data generated by various business systems, so that the data can be more conveniently applied. for subsequent decision-making and analysis. In the concept of a data warehouse, a task is a technical realization of the smallest data processing ...
