DataStudio supports default node types such as ODPS SQL and Shell nodes, and also allows you to create custom node types.

Prerequisites

DataWorks Enterprise Edition or a more advanced edition is activated so that you can use custom node type.

Limits

Only DataWorks Enterprise Edition or a more advanced edition supports the custom node type.

Go to the Node Config page

  1. Log on to the DataWorks console.
  2. In the left-side navigation pane, click Workspaces.
  3. In the top navigation bar, select the region where your workspace resides. On the Workspaces page, find your workspace and click DataStudio in the Actions column.
  4. Click Node Config in the upper-right corner of the DataStudio page. The Node Plugin list tab appears.
    The Node Config page consists of four tabs: Node Plugin list, Default Node Types, Custom Node Types, and Data quality plug-in list.Node Config page
    Important Only the owner and administrators of a workspace can perform operations on the Node Config page of the workspace.

View wrappers

A wrapper defines the core processing logic of a node type. Assume that you write an SQL statement in the code editor for an ODPS SQL node and commit the statement. In this case, DataWorks uses the wrapper for the specific ODPS SQL node type to parse and execute the statement. Before you create a custom node type, you must create a wrapper to develop the processing logic of the node type. You can use only Java to develop processing logic in a wrapper.

The Node Plugin list tab displays all existing wrappers. You can click Create in the upper-right corner to create a wrapper. For more information, see Create a wrapper.Node Plugin list tab
The values in the Latest Version, Version in Development Environment, and Version in Production Environment columns for each wrapper are displayed based on the following rules:
  • If the node is created but not deployed, Not Deployed is displayed.
  • If the node is deployed, the version and deployment time are displayed.
  • If the node is being deployed, Deploying is displayed.

View default node types

In the left-side navigation pane of the Node Config page, click Default Node Types to view values of Node Name and Tabs for each default node type. By default, DataStudio is displayed in the Tabs column.
Note You can only view data but cannot perform operations on the Default Node Types tab.

View custom node types

In the left-side navigation pane of the Node Config page, click Custom Node Types. On this tab, you can create, view, edit, and delete custom node types. These custom node types can be used on the DataStudio page. For more information, see Create a custom node type.Custom Node Types tab

View data quality wrappers

DataWorks allows you to create, deploy, and use data quality wrappers to satisfy diversified needs for data quality.

In the left-side navigation pane of the Node Config page, click Data quality plug-in list. On this tab, you can create, configure, view, and delete data quality wrappers.Data quality plug-in list tab
