type ClusterName:

string

param ClusterName:

[REQUIRED]

The cluster identifier. This parameter is stored as a lowercase string.

Constraints:

  • A name must contain from 1 to 20 alphanumeric characters or hyphens.

  • The first character must be a letter.

  • A name cannot end with a hyphen or contain two consecutive hyphens.

type NodeType:

string

param NodeType:

[REQUIRED]

The compute and memory capacity of the nodes in the cluster.

type Description:

string

param Description:

A description of the cluster.

type ReplicationFactor:

integer

param ReplicationFactor:

[REQUIRED]

The number of nodes in the DAX cluster. A replication factor of 1 will create a single-node cluster, without any read replicas. For additional fault tolerance, you can create a multiple node cluster with one or more read replicas. To do this, set ReplicationFactor to a number between 3 (one primary and two read replicas) and 10 (one primary and nine read replicas). If the AvailabilityZones parameter is provided, its length must equal the ReplicationFactor.

type AvailabilityZones:

list

param AvailabilityZones:

The Availability Zones (AZs) in which the cluster nodes will reside after the cluster has been created or updated. If provided, the length of this list must equal the ReplicationFactor parameter. If you omit this parameter, DAX will spread the nodes across Availability Zones for the highest availability.

  • (string) --

type SubnetGroupName:

string

param SubnetGroupName:

The name of the subnet group to be used for the replication group.

type SecurityGroupIds:

list

param SecurityGroupIds:

A list of security group IDs to be assigned to each node in the DAX cluster. (Each of the security group ID is system-generated.)

If this parameter is not specified, DAX assigns the default VPC security group to each node.

  • (string) --

type PreferredMaintenanceWindow:

string

param PreferredMaintenanceWindow:

Specifies the weekly time range during which maintenance on the DAX cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period. Valid values for ddd are:

  • sun

  • mon

  • tue

  • wed

  • thu

  • fri

  • sat

Example: sun:05:00-sun:09:00

type NotificationTopicArn:

string

param NotificationTopicArn:

The Amazon Resource Name (ARN) of the Amazon SNS topic to which notifications will be sent.

type IamRoleArn:

string

param IamRoleArn:

[REQUIRED]

A valid Amazon Resource Name (ARN) that identifies an IAM role. At runtime, DAX will assume this role and use the role's permissions to access DynamoDB on your behalf.

type ParameterGroupName:

string

param ParameterGroupName:

The parameter group to be associated with the DAX cluster.

type Tags:

list

param Tags:

A set of tags to associate with the DAX cluster.

  • (dict) --

    A description of a tag. Every tag is a key-value pair. You can add up to 50 tags to a single DAX cluster.

    AWS-assigned tag names and values are automatically assigned the aws: prefix, which the user cannot assign. AWS-assigned tag names do not count towards the tag limit of 50. User-assigned tag names have the prefix user:.

    You cannot backdate the application of a tag.

    • Key (string) --

      The key for the tag. Tag keys are case sensitive. Every DAX cluster can only have one tag with the same key. If you try to add an existing tag (same key), the existing tag value will be updated to the new value.

    • Value (string) --

      The value of the tag. Tag values are case-sensitive and can be null.

type SSESpecification:

dict

param SSESpecification:

Represents the settings used to enable server-side encryption on the cluster.

  • Enabled (boolean) -- [REQUIRED]

    Indicates whether server-side encryption is enabled (true) or disabled (false) on the cluster.

type ClusterEndpointEncryptionType:

string

param ClusterEndpointEncryptionType:

The type of encryption the cluster's endpoint should support. Values are:

  • NONE for no encryption

  • TLS for Transport Layer Security

Returns information about all provisioned DAX clusters if no cluster identifier is specified, or about a specific DAX cluster if a cluster identifier is supplied.

If the cluster is in the CREATING state, only cluster level information will be displayed until all of the nodes are successfully provisioned.

If the cluster is in the DELETING state, only cluster level information will be displayed.

If nodes are currently being added to the DAX cluster, node endpoint information and creation time for the additional nodes will not be displayed until they are completely provisioned. When the DAX cluster state is available, the cluster is ready for use.

If nodes are currently being removed from the DAX cluster, no endpoint information for the removed nodes is displayed.
