DescribeClusterParameters
Returns a detailed list of parameters contained within the specified Amazon Redshift parameter group. For each parameter the response includes information such as parameter name, description, data type, value, whether the parameter value is modifiable, and so on.
You can specify source filter to retrieve parameters of only specific type. For example, to retrieve parameters that were modified by a user action such as from ModifyClusterParameterGroup, you can specify source equal to user.
For more information about parameters and parameter groups, go to Amazon Redshift Parameter Groups in the Amazon Redshift Cluster Management Guide.
Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
- ParameterGroupName
-
The name of a cluster parameter group for which to return details.
Type: String
Length Constraints: Maximum length of 2147483647.
Required: Yes
- Marker
-
An optional parameter that specifies the starting point to return a set of response records. When the results of a DescribeClusterParameters request exceed the value specified in
MaxRecords, Amazon returns a value in theMarkerfield of the response. You can retrieve the next set of response records by providing the returned marker value in theMarkerparameter and retrying the request.Type: String
Length Constraints: Maximum length of 2147483647.
Required: No
- MaxRecords
-
The maximum number of response records to return in each call. If the number of remaining response records exceeds the specified
MaxRecordsvalue, a value is returned in amarkerfield of the response. You can retrieve the next set of records by retrying the command with the returned marker value.Default:
100Constraints: minimum 20, maximum 100.
Type: Integer
Required: No
- Source
-
The parameter types to return. Specify
userto show parameters that are different form the default. Similarly, specifyengine-defaultto show parameters that are the same as the default parameter group.Default: All parameter types returned.
Valid Values:
user|engine-defaultType: String
Length Constraints: Maximum length of 2147483647.
Required: No
Response Elements
The following elements are returned by the service.
- Marker
-
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
Markerparameter and retrying the command. If theMarkerfield is empty, all response records have been retrieved for the request.Type: String
Length Constraints: Maximum length of 2147483647.
- Parameters.Parameter.N
-
A list of Parameter instances. Each instance lists the parameters of one cluster parameter group.
Type: Array of Parameter objects
Errors
For information about the errors that are common to all actions, see Common Errors.
- ClusterParameterGroupNotFound
-
The parameter group name does not refer to an existing parameter group.
HTTP Status Code: 404
