Defined in:: (unknown)

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();

Version:

2017-04-19

The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com'.
accessKeyId (String) —
your AWS access key ID.
secretAccessKey (String) —
your AWS secret access key.
sessionToken (AWS.Credentials) —
the optional AWS session token to sign requests with.
credentials (AWS.Credentials) —
the AWS credentials to sign requests with. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.
credentialProvider (AWS.CredentialProviderChain) —
the provider chain used to resolve credentials if no static credentials property is set.
region (String) —
the region to send service requests to. See AWS.DAX.region for more information.
maxRetries (Integer) —
the maximum amount of retries to attempt with a request. See AWS.DAX.maxRetries for more information.
maxRedirects (Integer) —
the maximum amount of redirects to follow with a request. See AWS.DAX.maxRedirects for more information.
sslEnabled (Boolean) —
whether to enable SSL for requests.
paramValidation (Boolean|map) —
whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:
- min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
- max [Boolean] — Validates that a value meets the max constraint.
- pattern [Boolean] — Validates that a string value matches a regular expression.
- enum [Boolean] — Validates that a string value matches one of the allowable enum values.
computeChecksums (Boolean) —
whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)
convertResponseTypes (Boolean) —
whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.
correctClockSkew (Boolean) —
whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.
s3ForcePathStyle (Boolean) —
whether to force path style URLs for S3 objects.
s3BucketEndpoint (Boolean) —
whether the provided endpoint addresses an individual bucket (false if it addresses the root API endpoint). Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor.
s3DisableBodySigning (Boolean) —
whether S3 body signing should be disabled when using signature version v4. Body signing can only be disabled when using https. Defaults to true.
retryDelayOptions (map) —
A set of options to configure the retry delay on retryable errors. Currently supported options are:
- base [Integer] — The base number of milliseconds to use in the exponential backoff for operation retries. Defaults to 100 ms for all services except DynamoDB, where it defaults to 50ms.
- customBackoff [function] — A custom function that accepts a retry count and returns the amount of time to delay in milliseconds. The base option will be ignored if this option is supplied.
httpOptions (map) —
A set of options to pass to the low-level HTTP request. Currently supported options are:
- proxy [String] — the URL to proxy requests through
- agent [http.Agent, https.Agent] — the Agent object to perform HTTP requests with. Used for connection pooling. Defaults to the global agent (http.globalAgent) for non-SSL connections. Note that for SSL connections, a special Agent object is used in order to enable peer certificate verification. This feature is only available in the Node.js environment.
- connectTimeout [Integer] — Sets the socket to timeout after failing to establish a connection with the server after connectTimeout milliseconds. This timeout has no effect once a socket connection has been established.
- timeout [Integer] — Sets the socket to timeout after timeout milliseconds of inactivity on the socket. Defaults to two minutes (120000).
- xhrAsync [Boolean] — Whether the SDK will send asynchronous HTTP requests. Used in the browser environment only. Set to false to send requests synchronously. Defaults to true (async on).
- xhrWithCredentials [Boolean] — Sets the "withCredentials" property of an XMLHttpRequest object. Used in the browser environment only. Defaults to false.
apiVersion (String, Date) —

logger (#write, #log) —
an object that responds to .write() (like a stream) or .log() (like the console object) in order to log information about requests
systemClockOffset (Number) —
an offset value in milliseconds to apply to all signing times. Use this to compensate for clock skew when your system may be out of sync with the service time. Note that this configuration option can only be applied to the global AWS.config object and cannot be overridden in service-specific configuration. Defaults to 0 milliseconds.
signatureVersion (String) —
the signature version to sign requests with (overriding the API configuration). Possible values are: 'v2', 'v3', 'v4'.

Parameters:

params (Object) (defaults to: {}) —
- ClusterName — (String)
  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.
- NodeType — (String)
  The compute and memory capacity of the nodes in the cluster.
- Description — (String)
  A description of the cluster.
- ReplicationFactor — (Integer)
  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.
- AvailabilityZones — (Array<String>)
  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.
- SubnetGroupName — (String)
  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.
- SecurityGroupIds — (Array<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.
- PreferredMaintenanceWindow — (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
  
  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.
- NotificationTopicArn — (String)
  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.
- IamRoleArn — (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.
- ParameterGroupName — (String)
  The parameter group to be associated with the DAX cluster.
- Tags — (Array<map>)
  A set of tags to associate with the DAX cluster.
  - 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.
- SSESpecification — (map)
  Represents the settings used to enable server-side encryption on the cluster.
  - Enabled — required — (Boolean)
    Indicates whether server-side encryption is enabled (true) or disabled (false) on the cluster.

Returns:

(AWS.Request) —
a handle to the operation request for subsequent event callback registration.
