<p>The cluster identifier for the cluster that is being modified. This parameter is not case sensitive.</p> <p>Constraints:</p> <ul> <li> <p>Must match the identifier of an existing <code>DBCluster</code>.</p> </li> </ul>

<p>The new cluster identifier for the cluster when renaming a cluster.

If this parameter is set to <code>false</code>, changes to the cluster are applied during the next maintenance window.</p> <p>The <code>ApplyImmediately</code> parameter affects only the <code>NewDBClusterIdentifier</code> and <code>MasterUserPassword</code> values. If you set this parameter value to <code>false</code>, the changes to the <code>NewDBClusterIdentifier</code> and <code>MasterUserPassword</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.</p> <p>Default: <code>false</code> </p>

<p>The number of days for which automated backups are retained. You must specify a minimum value of 1.</p> <p>Default: 1</p> <p>Constraints:</p> <ul> <li> <p>Must be a value from 1 to 35.</p> </li> </ul>

The configuration setting for the log types to be enabled for export to Amazon CloudWatch Logs for a specific instance or cluster. The <code>EnableLogTypes</code> and <code>DisableLogTypes</code> arrays determine which logs are exported (or not exported) to CloudWatch Logs.

The version number of the database engine to which you want to upgrade. Modifying engine version is not supported on Amazon DocumentDB.

Specifies whether this cluster can be deleted. If <code>DeletionProtection</code> is enabled, the cluster cannot be deleted unless it is modified and <code>DeletionProtection</code> is disabled. <code>DeletionProtection</code> protects clusters from being accidentally deleted.
