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

Request
data DescribeClusterVersions Source
Request constructor
describeClusterVersions :: DescribeClusterVersions Source
DescribeClusterVersions
constructor.
The fields accessible through corresponding lenses are:
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
dcvClusterVersion :: Lens' DescribeClusterVersions (Maybe Text) Source
The specific cluster version to return.
Example: '1.0'
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.
Response
Response constructor
describeClusterVersionsResponse :: DescribeClusterVersionsResponse Source
DescribeClusterVersionsResponse
constructor.
The fields accessible through corresponding lenses are:
Response lenses
dcvrClusterVersions :: Lens' DescribeClusterVersionsResponse [ClusterVersion] Source
A list of Version
elements.
dcvrMarker :: 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.
