describe_default_cluster_parameters

Redshift.Client.describe_default_cluster_parameters(**kwargs)

Returns a list of parameter settings for the specified parameter group family.

For more information about parameters and parameter groups, go to Amazon Redshift Parameter Groups in the Amazon Redshift Cluster Management Guide.

Request Syntax

response = client.describe_default_cluster_parameters(
    ParameterGroupFamily='string',
    MaxRecords=123,
    Marker='string'
)

Parameters:

• ParameterGroupFamily (string) –

  [REQUIRED]

  The name of the cluster parameter group family.

• MaxRecords (integer) –

  The maximum number of response records to return in each call. If the number of remaining response records exceeds the specified MaxRecords value, a value is returned in a marker field of the response. You can retrieve the next set of records by retrying the command with the returned marker value.

  Default: 100

  Constraints: minimum 20, maximum 100.

• Marker (string) – An optional parameter that specifies the starting point to return a set of response records. When the results of a DescribeDefaultClusterParameters request exceed the value specified in MaxRecords, Amazon Web Services returns a value in the Marker field of the response. You can retrieve the next set of response records by providing the returned marker value in the Marker parameter and retrying the request.

Return type:

dict

Response Structure

• (dict) –

  • DefaultClusterParameters (dict) –

    Describes the default cluster parameters for a parameter group family.

    • ParameterGroupFamily (string) –

      The name of the cluster parameter group family to which the engine default parameters apply.

    • Marker (string) –

      A value that indicates the starting point for the next set of response records in a subsequent request. If a value is returned in a response, you can retrieve the next set of records by providing this returned marker value in the Marker parameter and retrying the command. If the Marker field is empty, all response records have been retrieved for the request.

    • Parameters (list) –

      The list of cluster default parameters.

      • (dict) –

        Describes a parameter in a cluster parameter group.

        • ParameterName (string) –

          The name of the parameter.

        • ParameterValue (string) –

          The value of the parameter. If ParameterName is wlm_json_configuration, then the maximum size of ParameterValue is 8000 characters.

        • Description (string) –

          A description of the parameter.

        • Source (string) –

          The source of the parameter value, such as “engine-default” or “user”.

        • DataType (string) –

          The data type of the parameter.

        • AllowedValues (string) –

          The valid range of values for the parameter.

        • ApplyType (string) –

          Specifies how to apply the WLM configuration parameter. Some properties can be applied dynamically, while other properties require that any associated clusters be rebooted for the configuration changes to be applied. For more information about parameters and parameter groups, go to Amazon Redshift Parameter Groups in the Amazon Redshift Cluster Management Guide.

        • IsModifiable (boolean) –

          If true, 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.
