Amazonka.DAX.Types.Tag

Documentation

data Tag

A description of a tag. Every tag is a key-value pair. You can add up to 50 tags to a single DAX cluster.

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:.

You cannot backdate the application of a tag.

See: newTag smart constructor.

Constructors

Tag'

Fields

• key :: Maybe Text

  The key for the tag. Tag keys are case sensitive. Every DAX cluster can only have 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 :: Maybe Text

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

newTag :: 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 for the tag. Tag keys are case sensitive. Every DAX cluster can only have 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 (Maybe Text)

The key for the tag. Tag keys are case sensitive. Every DAX cluster can only have 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 (Maybe Text)

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