  • Filters (list) –

    This parameter isn’t currently supported.

    • (dict) –

      A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.

      Note

      Currently, wildcards are not supported in filters.

      The following actions can be filtered:

      • DescribeDBClusterBacktracks

      • DescribeDBClusterEndpoints

      • DescribeDBClusters

      • DescribeDBInstances

      • DescribePendingMaintenanceActions

      • Name (string) – [REQUIRED]

        The name of the filter. Filter names are case-sensitive.

      • Values (list) – [REQUIRED]

        One or more filter values. Filter values are case-sensitive.

        • (string) –

  • MaxRecords (integer) –

    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 you can retrieve the remaining results.

    Default: 100

    Constraints: Minimum 20, maximum 100.

  • Marker (string) – An optional pagination token provided by a previous DescribeEngineDefaultParameters request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

Return type:

dict

Returns:
