-- | Creates a value of 'DeregisterScalableTarget' with the minimum fields required to make a request.

--
-- * 'derServiceNamespace' - The namespace of the AWS service. For more information, see <http://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#genref-aws-service-namespaces AWS Service Namespaces> in the /Amazon Web Services General Reference/ .
--
-- * 'derResourceId' - The identifier of the resource associated with the scalable target. This string consists of the resource type and unique identifier.     * ECS service - The resource type is @service@ and the unique identifier is the cluster name and service name. Example: @service/default/sample-webapp@ .     * Spot fleet request - The resource type is @spot-fleet-request@ and the unique identifier is the Spot fleet request ID. Example: @spot-fleet-request/sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE@ .     * EMR cluster - The resource type is @instancegroup@ and the unique identifier is the cluster ID and instance group ID. Example: @instancegroup/j-2EEZNYKUA1NTV/ig-1791Y4E1L8YI0@ .
--
-- * 'derScalableDimension' - The scalable dimension associated with the scalable target. This string consists of the service namespace, resource type, and scaling property.     * @ecs:service:DesiredCount@ - The desired task count of an ECS service.     * @ec2:spot-fleet-request:TargetCapacity@ - The target capacity of a Spot fleet request.     * @elasticmapreduce:instancegroup:InstanceCount@ - The instance count of an EMR Instance Group.
