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
- Log on to the DataWorks console.
- In the left-side navigation pane, click Workspaces.
- In the top navigation bar, select the region in which the workspace that you want
to manage resides. Find the workspace and click Data Development in the Actions column.
- 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.

Notice 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.

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.

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.
