string
[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.
string
[REQUIRED]
The compute and memory capacity of the nodes in the cluster.
string
A description of the cluster.
integer
[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 2 or more.
list
The Availability Zones (AZs) in which the cluster nodes will be created. All nodes belonging to the cluster are placed in these Availability Zones. Use this parameter if you want to distribute the nodes across multiple AZs.
(string) --
string
The name of the subnet group to be used for the replication group.
list
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) --
string
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
string
The Amazon Resource Name (ARN) of the Amazon SNS topic to which notifications will be sent.
string
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.
string
The parameter group to be associated with the DAX cluster.
list
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.
dict
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.

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 (dict) --
The configuration endpoint for this DAX cluster, consisting of a DNS name and a port number. Client applications can specify this endpoint, rather than an individual node endpoint, and allow the DAX client software to intelligently route requests and responses to nodes in the DAX cluster.

DISABLED - Server-side encryption is disabled.
{'Cluster': {'SSEDescription': {'Status': 'ENABLING | ENABLED | DISABLING | '
'DISABLED'}}}
Reboots a single node of a DAX cluster. The reboot action takes place as soon as possible. During the reboot, the node status is set to REBOOTING.
