Tag
Describes a tag. A tag is a key-value pair. You can add up to 50 tags to a single DynamoDB table.
AWS-assigned tag names and values are automatically assigned the
aws: prefix, which the user cannot assign. AWS-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.
For an overview on tagging DynamoDB resources, see Tagging for DynamoDB in the Amazon DynamoDB Developer Guide.
