Enhanced Datasource Connection Tag Management

Scenario

A tag is a key-value pair customized by users and used to identify cloud resources. It helps users to classify and search for cloud resources. A tag consists of a tag key and a tag value.

If you use tags in other cloud services, you are advised to create the same tag key-value pairs for cloud resources used by the same business to keep consistency.

DLI supports the following two types of tags:

• Resource tags: non-global tags created on DLI.

• Predefined tags: global tags created on Tag Management Service (TMS).

DLI allows you to add, modify, or delete tags for datasource connections.

Procedure

1. In the left navigation pane of the DLI management console, choose Datasource Connections.
2. In the Operation column of the link, choose More > Tags.
3. The tag management page is displayed, showing the tag information about the current connection.
4. Click Add/Edit Tag. The Add/Edit Tag dialog is displayed. Add or edit tag keys and values and click OK.
