Tag Management

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.

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 created on Tag Management Service (TMS). Predefined tags are global tags. For more information about predefined tags, see the Tag Management Service User Guide.

This section includes the following content:
