Managing Instance Tags

Tags facilitate Kafka instance identification and management.

You can add tags to a Kafka instance when creating the instance or add tags on the details page of the created instance. Up to 20 tags can be added to an instance. Tags can be modified and deleted.

A tag consists of a tag key and a tag value. Table 1 lists the tag key and value requirements.
