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 Amazon 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 Amazon account-based endpoints

DynamoDB offers Amazon account-based endpoints that can improve performance by using your Amazon 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 Amazon 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:

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