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, remove the following import:
Next, go to the
AmazonDynamoDB in the code:
AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard().withEndpointConfiguration( new AwsClientBuilder.EndpointConfiguration("http://localhost:8000", "us-west-2")) .build();
Now modify the client so that it will access an AWS region instead of a specific endpoint:
AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard() .withRegion(Regions.
For example, if you want to access the
us-west-2 region, you would do
AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard() .withRegion(Regions.US_WEST_2) .build();
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.
