Request Lenses

dcvClusterParameterGroupFamily :: Lens' DescribeClusterVersions (Maybe Text)

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)

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)

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)

The specific cluster version to return.

Example: '1.0'

Destructuring the Response

Response Lenses

dcvrsClusterVersions :: Lens' DescribeClusterVersionsResponse [ClusterVersion]

A list of Version elements.

dcvrsMarker :: Lens' DescribeClusterVersionsResponse (Maybe Text)

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

The response status code.
