Tag your Aiven resources#
Tags can add metadata to Aiven resources like projects and services. Adding tags can be useful to categorize services, store specific information to your application or business and to group services or bills depending on custom logic.
A tag consists of a string key and a single value and can be attached to any project or service.
Tag keys must consist of characters
[A-Za-z0-9_-], are case sensitive, and must start with a letter. The maximum length for a key is 64 characters.
Tag values can be at most 64 UTF-8 characters long.
Any single Aiven resource can have at most 10 tags attached. Within a resource, the tag keys are unique, meaning that there can’t be a duplicated key.
Tags are supported for Aiven projects and services. You currently need to either use the Aiven client, or call the tag APIs by some other means, to use tags. Aiven-client version 2.14.0 or later is required for tagging support.
