Managing Tags

Tag Management Service (TMS) enables you to manage resources using tags on the management console. TMS works with other cloud services to manage global tags, and other cloud services manage their own tags.

Adding tags to GeminiDB Cassandra instances helps you better identify and manage them. An instance can be tagged when or after it is created.

After an instance is tagged, you can search for the tag key or value to quickly query the instance details.

Precautions

  • You are advised to set predefined tags on the TMS console.
  • A tag consists of a key and value. You can add only one value for each key. For details about the naming rules of tag keys and tag values, see Table 1.
  • A maximum of 20 tags can be added for each instance.
  • The tag name must comply with the naming rules described in Table 1.
