A value that specifies whether the modifications in this request and any pending modifications are asynchronously
applied as soon as possible, regardless of the <code>PreferredMaintenanceWindow</code> setting for the DB
cluster. If this parameter is set to <code>false</code>, changes to the DB cluster are applied during the next
maintenance window.

<p>
The <code>ApplyImmediately</code> parameter only affects <code>NewDBClusterIdentifier</code> values. If you set
the <code>ApplyImmediately</code> parameter value to false, then changes to <code>NewDBClusterIdentifier</code>
values are applied during the next maintenance window. All other changes are applied immediately, regardless of
the value of the <code>ApplyImmediately</code> parameter.
