Amazon DynamoDB Accelerator (DAX)

2018/08/09 - Amazon DynamoDB Accelerator (DAX) - 7 updated api methods

Changes  Add the SSESpecification field to CreateCluster to allow creation of clusters with server-side encryption, and add the SSEDescription field to DescribeClusters to display the status of server-side encryption for a cluster.

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 2 or more.

Note

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

type AvailabilityZones

list

param AvailabilityZones

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) --

type SubnetGroupName

string

param SubnetGroupName

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

Warning

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.

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

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.

type NotificationTopicArn

string

param NotificationTopicArn

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.

type IamRoleArn

string

param IamRoleArn

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.

rtype

dict

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.
