View and manage task-related objects - Dataphin - Alibaba Cloud Documentation Center

Related objects of a computing task include tables referenced and read by the task, tables that reference and read the task, its dependent objects, and tasks that have it as an upstream dependency. This topic explains the process for viewing and managing a task's related objects.

Entry point for task-related objects

Navigate to the Dataphin home page, single click the top menu bar Development. You will be directed to the data Development page by default.
To view and manage related objects for a specific computing task, follow these steps to access the task-related objects management page:
Select project (Dev-Prod mode requires selecting the environment) -> single click Script Task -> choose the computing task of the related object -> single click Related.

Introduction to computing task-related objects

The computing task-related objects page provides details of the current task's associated objects, including input and output tables, dependent objects, and downstream tasks. Here, you can view and manage these related objects.

View input tables

Input tables are those referenced and read by the current task as part of its computing logic.

Area

Description

①Search and filter area

Filter: Supports filtering associated input tables based on the type of input table. Table types include logical dimension table, logical fact table, logical aggregate table, and physical table.
Search: Supports searching for associated input tables by input table name.

To update the list of task-related input tables, single click the refresh icon.

②Task input table list

This list presents the input tables associated with the current task, including their information and available operations.

Table information: Includes table name, table Chinese name, and table type.
Actions: To view the associated input table, simply single click the icon.

View output tables

Output tables are generated by the current task (the targets of insert into operations) and consist of tables written by the task.

Note

Tables written by the task are those present in the Dataphin asset directory. Tables written to external data sources in integration tasks are not considered output tables of the current task.

If the output tables related to the current task are not visible, try refreshing the list by single clicking.

②Task output table list

This list presents the output tables associated with the current task, including their information and available operations.

Table information: Includes table name, table Chinese name, and table type.
Actions: To view the associated output table, simply single click the icon.

View dependent objects

Dependent objects are those the computing task relies on, such as public calendars, global variables, resources, and Python third-party package objects.

Note

Resource and Python Module objects are only applicable to Shell and Python computing tasks.

Public calendar

To refresh the Python third-party package list, single click .

Python third-party package list

This list showcases the Python third-party packages associated with the current task, including their information and supported operations.

Object information: Includes the Python Module name and version.
Actions: To view the associated Python third-party packages, single click .

View downstream tasks

Downstream tasks are those that depend on the current task as an upstream dependency, including computing tasks, integration tasks, and logical tables.

Area

Description

①Search and filter area

Enables searching and filtering of downstream tasks by node ID or name. Single click to open the Filter dialog box for advanced filtering.

The filter dialog box allows for filtering downstream tasks based on node type, reference parameters, project/section, scheduling cycle, and operation owner.

Node Type: Filters by physical node and logical table node.
Reference Parameters: Filters by cross-node parameters referenced.
Project/Section: Filters by project or data section of the downstream task.
Scheduling Cycle: Filters by scheduling cycles such as monthly, weekly, hourly, minutely, and daily.
Operation Owner: Filters by the owner of the operation.

If the necessary downstream tasks do not appear, attempt to refresh the list by single clicking.

②Downstream task list

This list displays information on the downstream tasks and the operations they support.

Downstream task information: Includes downstream node name/ID, node type, reference parameters, project/section, scheduling cycle, owner.
Actions: Single click to display the current downstream tasks.
