Creates and binds tags to one or more ApsaraDB for RDS instances.

If you have a large number of instances, you can create multiple tags and bind these tags to the instances. Then, you can filter the instances by tag.

  • A tag consists of a key and a value. Each key must be unique in a region for an Alibaba Cloud account. Different keys can be mapped to the same value.
  • If a specified tag does not exist, the tag is created and bound to the specified instances.
  • If the key of the specified tag is the same as that of an existing tag, the specified tag overwrites the existing tag.
  • You can bind up to 20 tags to an instance.
  • You can bind tags to up to 50 instances in each call.
