Request Syntax

response = client.describe_db_cluster_parameters(
    DBClusterParameterGroupName='string',
    Source='string',
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    MaxRecords=123,
    Marker='string'
)
Parameters:

  • DBClusterParameterGroupName (string) –

    [REQUIRED]

    The name of a specific DB cluster parameter group to return parameter details for.

    Constraints:

    • If supplied, must match the name of an existing DBClusterParameterGroup.

  • Source (string) –

    A specific source to return parameters for.

    Valid Values:

    • customer

    • engine

    • service

  • 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

      • DescribeDBRecommendations

      • DescribeDBShardGroups

      • 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 DescribeDBClusterParameters request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

Return type:

dict

Response Structure

  • (dict) –

    Provides details about a DB cluster parameter group including the parameters in the DB cluster parameter group.

    • Parameters (list) –

      Provides a list of parameters for the DB cluster parameter group.

      • (dict) –

        This data type is used as a request parameter in the ModifyDBParameterGroup and ResetDBParameterGroup actions.

        This data type is used as a response element in the DescribeEngineDefaultParameters and DescribeDBParameters actions.

        • ParameterName (string) –

          The name of the parameter.

        • ParameterValue (string) –

          The value of the parameter.

        • Description (string) –

          Provides a description of the parameter.

        • Source (string) –

          The source of the parameter value.

        • ApplyType (string) –

          Specifies the engine specific parameters type.

        • DataType (string) –

          Specifies the valid data type for the parameter.

        • AllowedValues (string) –

          Specifies the valid range of values for the parameter.

        • IsModifiable (boolean) –

          Indicates whether ( true) or not ( false) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.

        • MinimumEngineVersion (string) –

          The earliest engine version to which the parameter can apply.

        • ApplyMethod (string) –

          Indicates when to apply parameter updates.

        • SupportedEngineModes (list) –

          The valid DB engine modes.

          • (string) –

    • Marker (string) –

      An optional pagination token provided by a previous DescribeDBClusterParameters request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.
