Options

--cluster-name (string)

The name of the DAX cluster to be modified.

--description (string)

A description of the changes being made to the cluster.

--preferred-maintenance-window (string)

A range of time when maintenance of DAX cluster software will be performed. For example: sun:01:00-sun:09:00 . Cluster maintenance normally takes less than 30 minutes, and is performed automatically within the maintenance window.

--notification-topic-arn (string)

The Amazon Resource Name (ARN) that identifies the topic.

--notification-topic-status (string)

The current state of the topic. A value of “active” means that notifications will be sent to the topic. A value of “inactive” means that notifications will not be sent to the topic.

--parameter-group-name (string)

The name of a parameter group for this cluster.

--security-group-ids (list)

A list of user-specified security group IDs to be assigned to each node in the DAX cluster. If this parameter is not specified, DAX assigns the default VPC security group to each node.

(string)

Syntax:

"string" "string" ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

Cluster -> (structure)

A description of the DAX cluster, after it has been modified.

ClusterName -> (string)

The name of the DAX cluster.

Description -> (string)

The description of the cluster.

ClusterArn -> (string)

The Amazon Resource Name (ARN) that uniquely identifies the cluster.

TotalNodes -> (integer)

The total number of nodes in the cluster.

ActiveNodes -> (integer)

The number of nodes in the cluster that are active (i.e., capable of serving requests).

NodeType -> (string)

The node type for the nodes in the cluster. (All nodes in a DAX cluster are of the same type.)

Status -> (string)

The current status of the cluster.

ClusterDiscoveryEndpoint -> (structure)

The endpoint for this DAX cluster, consisting of a DNS name, a port number, and a URL. Applications should use the URL to configure the DAX client to find their cluster.

Address -> (string)

The DNS hostname of the endpoint.

Port -> (integer)

The port number that applications should use to connect to the endpoint.

URL -> (string)

The URL that applications should use to connect to the endpoint. The default ports are 8111 for the "dax" protocol and 9111 for the "daxs" protocol.

NodeIdsToRemove -> (list)

A list of nodes to be removed from the cluster.

(string)

Nodes -> (list)

A list of nodes that are currently in the cluster.

(structure)

Represents an individual node within a DAX cluster.

NodeId -> (string)

A system-generated identifier for the node.

Endpoint -> (structure)

The endpoint for the node, consisting of a DNS name and a port number. Client applications can connect directly to a node endpoint, if desired (as an alternative to allowing DAX client software to intelligently route requests and responses to nodes in the DAX cluster.

Address -> (string)

The DNS hostname of the endpoint.

Port -> (integer)

The port number that applications should use to connect to the endpoint.
