Class Tag

  • All Implemented Interfaces:
    Serializable, SdkPojo, ToCopyableBuilder<Tag.Builder,​Tag>
    @Generated("software.amazon.awssdk:codegen")
public final class Tag
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Tag.Builder,​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.

    For an overview on tagging DynamoDB resources, see Tagging for DynamoDB in the Amazon DynamoDB Developer Guide.
