-- | Configures scaling parameters for a domain. A domain's scaling parameters
-- specify the desired search instance type and replication count. Amazon
-- CloudSearch will still automatically scale your domain based on the volume of
-- data and traffic, but not below the desired instance type and replication
-- count. If the Multi-AZ option is enabled, these values control the resources
-- used per Availability Zone. For more information, see Configuring Scaling
-- Options in the /Amazon CloudSearch Developer Guide/.
