Adding Tags to a Flink Job

A tag is a user-defined key-value pair used to identify cloud resources, helping you classify and search for them. A tag consists of a tag key and a tag value.

DLI allows you to add tags to Flink jobs. You can add tags to Flink jobs to identify information such as the project name, service type, and background. 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: indicate non-global tags created on DLI.
• Predefined tags: global tags created on Tag Management Service (TMS).

  For details about predefined tags, see Tag Management Service User Guide.
