Amazon DynamoDB
Getting Started Guide (API Version 2012-08-10)

Summary

In this tutorial, you created the Movies table in DynamoDB on your computer and performed basic operations. The downloadable version of DynamoDB is useful during application development and testing. However, when you are ready to run your application in a production environment, you need to modify your code so that it uses the Amazon DynamoDB web service.

Using the Amazon DynamoDB Service

You need to change the endpoint in your application in order to use the Amazon DynamoDB service. To do this, add the following import statement to your program:

import com.amazonaws.regions.Regions;

Next, go to the AmazonDynamoDBClient in the code:

AmazonDynamoDBClient client = new AmazonDynamoDBClient()
.withEndpoint("http://localhost:8000");

Now modify the client so that it will access an AWS region instead of a specific endpoint:

AmazonDynamoDBClient client = new AmazonDynamoDBClient()
.withRegion(Regions.REGION);

For example, if you want to access the us-west-2 region, you would do this:

AmazonDynamoDBClient client = new AmazonDynamoDBClient()
.withRegion(Regions.US_WEST_2);

Instead of using DynamoDB on your computer, the program now uses the Amazon DynamoDB web service endpoint in US West (Oregon).

Amazon DynamoDB is available in several regions worldwide. For the complete list, see Regions and Endpoints in the AWS General Reference. For more information about setting regions and endpoints in your code, see AWS Region Selection in the AWS SDK for Java Developer Guide.

Finally, we recommend that you read the Amazon DynamoDB Developer Guide. It provides more in-depth information about DynamoDB, including sample code and best practices.
