Returns descriptions of the available Amazon Redshift cluster versions. You can call this operation even before creating any clusters to learn more about the Amazon Redshift versions. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide
See: AWS API Reference for DescribeClusterVersions.
This operation returns paginated results.

Creating a Request
describeClusterVersions :: DescribeClusterVersions Source
Creates a value of DescribeClusterVersions
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data DescribeClusterVersions Source
See: describeClusterVersions
smart constructor.
Request Lenses
dcvClusterParameterGroupFamily :: Lens' DescribeClusterVersions (Maybe Text) Source
The name of a specific cluster parameter group family to return details for.
Constraints:
- Must be 1 to 255 alphanumeric characters
- First character must be a letter
- Cannot end with a hyphen or contain two consecutive hyphens
dcvMarker :: Lens' DescribeClusterVersions (Maybe Text) Source
An optional parameter that specifies the starting point to return a set
of response records. When the results of a DescribeClusterVersions
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.
dcvMaxRecords :: Lens' DescribeClusterVersions (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.
dcvClusterVersion :: Lens' DescribeClusterVersions (Maybe Text) Source
The specific cluster version to return.
Example: '1.0'
Destructuring the Response
describeClusterVersionsResponse Source
Creates a value of DescribeClusterVersionsResponse
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data DescribeClusterVersionsResponse Source
Contains the output from the DescribeClusterVersions action.
See: describeClusterVersionsResponse
smart constructor.
Response Lenses
dcvrsClusterVersions :: Lens' DescribeClusterVersionsResponse [ClusterVersion] Source
A list of Version
elements.
dcvrsMarker :: Lens' DescribeClusterVersionsResponse (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.
dcvrsResponseStatus :: Lens' DescribeClusterVersionsResponse Int Source
The response status code.
