Configuring
AWS SDK V3
If you are using the AWS SDK V3, import the AWS V3 DynamoDBClient class. Then create a DynamoDBClient instance.
AWS SDK V2
If you are using the legacy AWS SDK V2, import the AWS V2 SDK DynamoDB class and create a DocumentClient instance.
Note: you can use the Table.setClient API to defer setting the client or replace the client at any time.
