#
# * AllocatedStorage <~Integer> Storage space, in GB
# * AllowMajorVersionUpgrade <~Boolean> Must be set to true if EngineVersion specifies a different major version
# * AutoMinorVersionUpgrade <~Boolean> Indicates that minor version upgrades will be applied automatically to the DB Instance during the maintenance window
# * BackupRetentionPeriod <~Integer> 0-8 The number of days to retain automated backups.
# * DBInstanceClass <~String> The new compute and memory capacity of the DB Instanc
# * DBParameterGroupName <~String> The name of the DB Parameter Group to apply to this DB Instance

# * EngineVersion <~String> The version number of the database engine to upgrade to.
# * Iops <~Integer> IOPS rate
# * MasterUserPassword <~String> The new password for the DB Instance master user
# * MultiAZ <~Boolean> Specifies if the DB Instance is a Multi-AZ deployment
# * PreferredBackupWindow <~String> The daily time range during which automated backups are created if automated backups are enabled
# * PreferredMaintenanceWindow <~String> The weekly time range (in UTC) during which system maintenance can occur, which may result in an outage
