CreateClusterRequest
import type { CreateClusterRequest } from "https://aws-api.deno.dev/v0.3/services/dax.ts?docs=full";
§Properties
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.
The type of encryption the cluster's endpoint should support. Values are:
NONE
for no encryptionTLS
for Transport Layer Security
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.
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.
The Amazon Resource Name (ARN) of the Amazon SNS topic to which notifications will be sent.
Note: The Amazon SNS topic owner must be same as the DAX cluster owner.
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
Note: If you don't specify a preferred maintenance window when you create or modify a cache cluster, DAX assigns a 60-minute maintenance window on a randomly selected day of the week.
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
.
Note: AWS recommends that you have at least two read replicas per cluster.
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.
Represents the settings used to enable server-side encryption on the cluster.
