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:

  • engine-default

  • system

  • user

• Filters (list) –

  A filter that specifies one or more DB cluster parameters to describe.

  The only supported filter is parameter-name. The results list only includes information about the DB cluster parameters with these names.

  • (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

Returns:

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.

Exceptions

• RDS.Client.exceptions.DBParameterGroupNotFoundFault

Examples

This example lists system parameters for the specified DB cluster parameter group.

response = client.describe_db_cluster_parameters(
    DBClusterParameterGroupName='mydbclusterparametergroup',
    Source='system',
)

print(response)
