Overview
Constructs a service interface object. Each API operation is exposed as a function on service.
Service Description
DAX is a managed caching service engineered for Amazon DynamoDB. DAX dramatically speeds up database reads by caching frequently-accessed data from DynamoDB, so applications can access that data with sub-millisecond latency. You can create a DAX cluster easily, using the AWS Management Console. With a few simple modifications to your code, your application can begin taking advantage of the DAX cluster and realize significant improvements in read performance.
Sending a Request Using DAX
var dax = new AWS.DAX();
dax.createCluster(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
Locking the API Version
In order to ensure that the DAX object uses this specific API, you can
construct the object by passing the apiVersion
option to the constructor:
var dax = new AWS.DAX({apiVersion: '2017-04-19'});
You can also set the API version globally in AWS.config.apiVersions
using
the dax service identifier:
AWS.config.apiVersions = {
dax: '2017-04-19',
// other service API versions
};
var dax = new AWS.DAX();

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 theReplicationFactor

ReplicationFactor
parameter. If you omit this parameter, DAX will spread the nodes across Availability Zones for the highest availability.SubnetGroupName

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

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