Work with DynamoDB - AWS SDK for Java 2.x
Use AWS account-based endpoints

Work with DynamoDB

This section provides examples that show you how to work with DynamoDB.

The following examples use the standard, low-level DynamoDB client (DynamoDbClient) of the AWS SDK for Java 2.x.

The SDK also offers the DynamoDB Enhanced Client that provides a high-level, object-oriented approach for working with DynamoDB. The following section discusses this client in depth.

Use AWS account-based endpoints

DynamoDB offers AWS account-based endpoints that can improve performance by using your AWS account ID to streamline request routing.

To take advantage of this feature, you need to use version 2.28.4 or greater of version 2 of AWS SDK for Java. You can find the latest version of the SDK listed in the Maven central repository. After a supported version of SDK is active, it automatically uses the new endpoints.

If you want to opt out of the account-based routing, you have four options:

  • Configure a DynamoDB service client with the AccountIdEndpointMode set to DISABLED.

  • Set an environment variable.

  • Set a JVM system property.

  • Update the shared AWS config file setting.

The following snippet is an example of how to disable account-based routing by configuring a DynamoDB service client:

DynamoDbClient.builder()
              .accountIdEndpointMode(AccountIdEndpointMode.DISABLED)
              .build();

The AWS SDKs and Tools Reference Guide provides more information on the last three configuration options.
