-- | Creates a DB instance that acts as a read replica of a source DB instance.
--
-- All read replica DB instances are created as Single-AZ deployments with
-- backups disabled. All other DB instance attributes (including DB security
-- groups and DB parameter groups) are inherited from the source DB instance,
-- except as specified below.
--
-- The source DB instance must have backup retention enabled.

-- Constraints:

-- region in which the operation is running.  All read replicas in one region
-- that are created from the same source DB instance must either:  Specify DB

--
-- Default: The default behavior varies depending on whether a VPC has been
-- requested or not. The following list shows the default behavior in each case.
--
-- Default VPC:true  VPC:false   If no DB subnet group has been specified as
-- part of the request and the PubliclyAccessible value has not been set, the DB

-- Must be the identifier of an existing DB instance. Can specify a DB
-- instance that is a read replica only if the source is running MySQL 5.6. The
-- specified DB instance must have automatic backups enabled, its backup
-- retention period must be greater than 0. If the source DB instance is in the
-- same region as the read replica, specify a valid DB instance identifier. If
-- the source DB instance is in a different region than the read replica,
-- specify a valid DB instance ARN. For more information, go to <http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Tagging.html#USER_Tagging.ARN  Constructing aAmazon RDS Amazon Resource Name (ARN)>.
