Dynamic Route for CDN (DCDN) allows you to add tags to domain names. You can use tags to mark and group domain names, and filter domain names by tag. This facilitates the management of domain names.
Tags can be used to mark domain names. Each tag consists of a key-value pair. After you add a large number of domain names to DCDN, domain names may become difficult to manage. In this case, you can use tags to group domain names. This way, you can search and filter data by tag.
A company has added 100 domain names to DCDN. These domain names are used to provide services such as marketing, Game A, Game B, and post-production. The company has three O&M engineers: Alice, Tom, and Sam.
|Tag key||Tag value|
|Department||E-commerce, Game, and Entertainment|
|Service||Marketing, Game A, Game B, and Post-production|
|Responsible engineer||Alice, Tom, and Sam|
|Domain name||Value (key is Department)||Value (key is Service)||Value (key is Responsible engineer)|
- If you want to search for domain names that are managed by Sam, filter domain names by the following tag: Responsible engineer: Sam.
- If you want to search for domain names that belong to the game department and are managed by Tom, filter domain names by the following tags: Department: Game and Responsible engineer: Tom.
- You can add at most 20 tags to each domain name.
- The keys of tags that are added to the same domain name must be unique.
If two tags added to the same domain name have the same key but different values, the tag added later overwrites the one added earlier. For example, if you add tags
Key1:Value2to the domain name
test.example.com, only the tag
Key1:Value2is added to the domain name
