tag_value :: Lens' Tag Text

Documentation

data Tag Source #

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.

See: newTag smart constructor.

Constructors

Tag'
Fields key :: Text The key of the tag. Tag keys are case sensitive. Each DynamoDB table can only have up to one tag with the same key. If you try to add an existing tag (same key), the existing tag value will be updated to the new value. value :: Text The value of the tag. Tag values are case-sensitive and can be null.

Arguments

:: Text	`$sel:key:Tag'`
-> Text	`$sel:value:Tag'`
-> Tag

Create a value of Tag with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:key:Tag', tag_key - The key of the tag. Tag keys are case sensitive. Each DynamoDB table can only have up to one tag with the same key. If you try to add an existing tag (same key), the existing tag value will be updated to the new value.

$sel:value:Tag', tag_value - The value of the tag. Tag values are case-sensitive and can be null.

tag_key :: Lens' Tag Text Source #

The key of the tag. Tag keys are case sensitive. Each DynamoDB table can only have up to one tag with the same key. If you try to add an existing tag (same key), the existing tag value will be updated to the new value.

tag_value :: Lens' Tag Text Source #

The value of the tag. Tag values are case-sensitive and can be null.
