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.
This operation returns paginated results.

Creating a Request
describeClusterParameters Source #
Creates a value of DescribeClusterParameters
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data DescribeClusterParameters Source #
See: describeClusterParameters
smart constructor.
Request Lenses
dcpsMarker :: Lens' DescribeClusterParameters (Maybe Text) Source #
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
, AWS 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.
dcpsMaxRecords :: Lens' DescribeClusterParameters (Maybe Int) Source #
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.
dcpsSource :: Lens' DescribeClusterParameters (Maybe Text) Source #
The parameter types to return. Specify user
to show parameters that are different form the default. Similarly, specify 'engine-default' to show parameters that are the same as the default parameter group.
Default: All parameter types returned.
Valid Values: user
| 'engine-default'
dcpsParameterGroupName :: Lens' DescribeClusterParameters Text Source #
The name of a cluster parameter group for which to return details.
Destructuring the Response
describeClusterParametersResponse Source #
Creates a value of DescribeClusterParametersResponse
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data DescribeClusterParametersResponse Source #
Contains the output from the DescribeClusterParameters action.
See: describeClusterParametersResponse
smart constructor.
Response Lenses
dcprsMarker :: Lens' DescribeClusterParametersResponse (Maybe Text) Source #
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.
dcprsParameters :: Lens' DescribeClusterParametersResponse [Parameter] Source #
A list of Parameter instances. Each instance lists the parameters of one cluster parameter group.
dcprsResponseStatus :: Lens' DescribeClusterParametersResponse Int Source #
The response status code.
