Implementations§

source §

impl CreateClusterInput

source

pub async fn make_operation(
&self,
_config: &Config
) -> Result<Operation<CreateCluster, AwsResponseRetryClassifier>, BuildError>

Consumes the builder and constructs an Operation<CreateCluster>

source

pub fn builder() -> Builder

Creates a new builder-style object to manufacture CreateClusterInput.

impl CreateClusterInput

source

pub fn cluster_name(&self) -> Option<&str>

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.

source

pub fn node_type(&self) -> Option<&str>

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

source

pub fn description(&self) -> Option<&str>

A description of the cluster.

source

pub fn replication_factor(&self) -> i32

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.

AWS recommends that you have at least two read replicas per cluster.

source

pub fn availability_zones(&self) -> Option<&[String]>

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.

source

pub fn subnet_group_name(&self) -> Option<&str>

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

DAX clusters can only run in an Amazon VPC environment. All of the subnets that you specify in a subnet group must exist in the same VPC.

source

pub fn security_group_ids(&self) -> Option<&[String]>

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.

source

pub fn preferred_maintenance_window(&self) -> Option<&str>

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

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.

source

pub fn notification_topic_arn(&self) -> Option<&str>

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

The Amazon SNS topic owner must be same as the DAX cluster owner.

source

pub fn iam_role_arn(&self) -> Option<&str>

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.
