Tags let you organize and manage large numbers of ApsaraDB RDS for SQL Server instances. Each tag is a key-value pair attached to an instance—use the key to define a category (such as environment or team) and the value to specify the classification within that category (such as production or backend).
Limits
| Constraint | Detail |
|---|---|
| Tags per instance | Up to 20 |
| Tag key uniqueness | Each key must be unique per instance. A tag with a duplicate key overwrites the existing tag. |
| Batch operation limit | Up to 50 instances can be tagged in a single operation |
| Tag namespace scope | Regional. Instances in different regions do not share a tag namespace. |
| Tag deletion | When you remove a tag from an instance, ApsaraDB RDS deletes the tag if no other instance in the region uses it. |
