Tags are key-value pairs that let you classify and manage RDS instances at scale. For example, the tag Environment = Production identifies instances running your production workload. Use tags to group instances by team, environment, or cost center—then filter, search, or apply bulk operations across those groupings.
Limits
Each RDS instance supports up to 20 tags.
Each tag key must be unique within an instance. If two tags share the same key, the later tag overwrites the earlier one.
Tags are scoped to a region. Instances in different regions do not share a tag namespace.
You can add tags to up to 50 RDS instances in a single batch operation.
When you remove a tag from an RDS instance, ApsaraDB RDS checks whether the tag is attached to any other instance. If not, ApsaraDB RDS deletes the tag.
