Tag
class Tag
Describes a tag. A tag is a key-value pair. You can add up to 50 tags to a single DynamoDB table.
Amazon Web Services-assigned tag names and values are automatically assigned the aws:
prefix, which the user cannot assign. Amazon Web Services-assigned tag names do not count towards the tag limit of 50. User-assigned tag names have the prefix user:
in the Cost Allocation Report. You cannot backdate the application of a tag.
