<p>The user-supplied DB cluster identifier. If this parameter is specified, information from only the specific DB cluster is returned. This parameter isn't case-sensitive.</p> <p>Constraints:</p> <ul> <li> <p>If supplied, must match an existing DBClusterIdentifier.</p> </li> </ul>

<p>A filter that specifies one or more DB clusters to describe.</p> <p>Supported filters:</p> <ul> <li> <p> <code>db-cluster-id</code> - Accepts DB cluster identifiers and DB cluster Amazon Resource Names (ARNs). The results list will only include information about the DB clusters identified by these ARNs.</p> </li> <li> <p> <code>engine</code> - Accepts an engine name (such as <code>neptune</code>), and restricts the results list to DB clusters created by that engine.</p> </li> </ul> <p>For example, to invoke this API from the Amazon CLI and filter so that only Neptune DB clusters are returned, you could use the following command:</p>

<p>The maximum number of records to include in the response. If more records exist than the specified <code>MaxRecords</code> value, a pagination token called a marker is included in the response so that the remaining results can be retrieved.</p> <p>Default: 100</p> <p>Constraints: Minimum 20, maximum 100.</p>
