GlobalClusterIdentifier: The user-supplied cluster identifier. If this parameter is specified, information from only the specific cluster is returned. This parameter isn't case-sensitive.
Filters: A filter that specifies one or more global DB clusters to describe.
Supported filters: db-cluster-id accepts cluster identifiers and cluster Amazon Resource Names (ARNs). The results list will only include information about the clusters identified by these ARNs.
MaxRecords: The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a pagination token called a marker is included in the response so that you can retrieve the remaining results.
Marker: An optional pagination token provided by a previous describe_global_clusters request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.
