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 help’ for descriptions of global parameters.
describe-cluster-versions
is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate
argument.
When using --output text
and the --query
argument on a paginated response, the --query
argument must extract data from the results of the following query expressions: ClusterVersions
describe-cluster-versions
[--cluster-version <value>]
[--cluster-parameter-group-family <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
--cluster-version
(string)
The specific cluster version to return.
Example:
1.0
--cluster-parameter-group-family
(string)
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
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--starting-token
(string)
A token to specify where to start paginating. This is the
NextToken
from a previously truncated response.For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--page-size
(integer)
The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.
For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--max-items
(integer)
The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a
NextToken
is provided in the command’s output. To resume pagination, provide theNextToken
value in thestarting-token
argument of a subsequent command. Do not use theNextToken
response element directly outside of the AWS CLI.For usage examples, see Pagination in the AWS Command Line Interface User Guide .
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
This example returns a description of all cluster versions. By default, the output is in JSON format.
Command:
aws redshift describe-cluster-versions
Result:
{
"ClusterVersions": [
{
"ClusterVersion": "1.0",
"Description": "Initial release",
"ClusterParameterGroupFamily": "redshift-1.0"
} ],
"ResponseMetadata": {
"RequestId": "16a53de3-64cc-11e2-bec0-17624ad140dd"
}
}
Marker -> (string)
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 theMarker
field is empty, all response records have been retrieved for the request.
ClusterVersions -> (list)
A list of
Version
elements.(structure)
Describes a cluster version, including the parameter group family and description of the version.
ClusterVersion -> (string)
The version number used by the cluster.
ClusterParameterGroupFamily -> (string)
The name of the cluster parameter group family for the cluster.
Description -> (string)
The description of the cluster version.
