@ThreadSafe
public class AWSIotDataAsyncClient
extends AWSIotDataClient
implements AWSIotDataAsync

Interface for accessing AWS IoT Data Plane asynchronously. Each asynchronous method will return a Java Future object representing the asynchronous operation; overloads which accept an AsyncHandler can be used to receive notification when an asynchronous operation completes.

AWS IoT

AWS IoT-Data enables secure, bi-directional communication between Internet-connected things (such as sensors, actuators, embedded devices, or smart appliances) and the AWS cloud. It implements a broker for applications and things to publish messages over HTTP (Publish) and retrieve, update, and delete thing shadows. A thing shadow is a persistent representation of your things and their state in the AWS cloud.

Constructor Detail

AWSIotDataAsyncClient

public AWSIotDataAsyncClient()

Constructs a new asynchronous client to invoke service methods on AWS IoT Data Plane. A credentials provider chain will be used that searches for credentials in this order:

• Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
• Java System Properties - aws.accessKeyId and aws.secretKey
• Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
• Instance profile credentials delivered through the Amazon EC2 metadata service

Asynchronous methods are delegated to a fixed-size thread pool containing 50 threads (to match the default maximum number of concurrent connections to the service).

DefaultAWSCredentialsProviderChain, Executors.newFixedThreadPool(int)

• Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
