Use AWS account-based endpoints with DynamoDB - AWS SDK for JavaScript

The AWS SDK for JavaScript V3 API Reference Guide describes in detail all the API operations for the AWS SDK for JavaScript version 3 (V3).

Use AWS account-based endpoints with DynamoDB

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 3.656.0 or greater of AWS SDK for JavaScript version 3. This account-based endpoints feature is enabled by default in this new version.

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

  • Configure a DynamoDB service client with the accountIdEndpointMode parameter set to disabled.

  • Set the environment variable AWS_ACCOUNT_ID_ENDPOINT_MODE to disabled.

  • Update the shared AWS config file setting account_id_endpoint_mode to disabled.

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

const ddbClient = new DynamoDBClient({
  region: "us-west-2",
  accountIdEndpointMode: "disabled" // Disable account ID in the endpoint
});

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