  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 the target workspace resides. Find the target workspace and click Data Analytics in the Actions column.
  4. On the DataStudio page, click Node Config in the top navigation bar. 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
    Notice Only the owner and administrators of a workspace can perform operations on the Node Config page of the workspace.

View the list of wrappers

A wrapper defines the core processing logic of a node type. For example, after you write an SQL statement in the code editor for an ODPS SQL node and commit the statement, DataWorks uses the wrapper for the 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 the wrappers in the current workspace. You can click Create in the upper-right corner to create a wrapper.Node Plugin list tab
The values that are displayed in the Latest Version, Version in Development Environment, and Version in Production Environment columns for each wrapper follow these rules:
  • If the wrapper is created and not deployed to the development environment, the values in the Version in Development Environment and Version in Production Environment columns are both Not Published.
  • If the wrapper has been deployed, the version and the deployment time appear in these columns.
  • If the wrapper is being deployed to the production environment, the values in the Version in Development Environment and Version in Production Environment columns are both Publishing.

View default node types

In the left-side navigation pane of the Node Config page, click Default Node Types. The table on this tab has two columns: Node Name and Tabs, which respectively indicate the name of each node type and the one or more services where the node type can be used. By default, DataStudio is displayed in the Tabs column.
Note You cannot perform operations on the Default Node Types tab.

Manage custom node types

In the left-side navigation pane of the Node Config tab, click Custom Node Types. On this tab, you can create, view, edit, or delete custom node types. These custom node types can be used on the DataStudio page. Custom Node Types tab

View data quality wrappers

DataWorks allows you to create, deploy, and use data quality wrappers based on your needs.

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. For more information, see Create a data quality wrapper.Data quality plug-in list tab
