Amazonka.EMR.Types.Tag

Description

Synopsis

data Tag = Tag' {
- key :: Maybe Text
- value :: Maybe Text
}
newTag :: Tag
tag_key :: Lens' Tag (Maybe Text)
tag_value :: Lens' Tag (Maybe Text)

Documentation

data Tag Source #

A key-value pair containing user-defined metadata that you can associate with an Amazon EMR resource. Tags make it easier to associate clusters in various ways, such as grouping clusters to track your Amazon EMR resource allocation costs. For more information, see Tag Clusters.

See: newTag smart constructor.

Constructors

Tag'
Fields key :: Maybe Text A user-defined key, which is the minimum required information for a valid tag. For more information, see Tag. value :: Maybe Text A user-defined value, which is optional in a tag. For more information, see Tag Clusters.

newTag :: Tag Source #

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 - A user-defined key, which is the minimum required information for a valid tag. For more information, see Tag.

$sel:value:Tag', tag_value - A user-defined value, which is optional in a tag. For more information, see Tag Clusters.

tag_key :: Lens' Tag (Maybe Text) Source #

A user-defined key, which is the minimum required information for a valid tag. For more information, see Tag.

tag_value :: Lens' Tag (Maybe Text) Source #

A user-defined value, which is optional in a tag. For more information, see Tag Clusters.
