-If you are using the legacy AWS SDK V2, import the AWS `DynamoDB` class and create a `DocumentClient` instance.

-import DynamoDB from 'aws-sdk/clients/dynamodb'
-const client = new DynamoDB.DocumentClient(params)
-```

 Note: you can use the Table.setClient API to defer setting the client or replace the client at any time.
 
 Initialize your OneTable `Table` instance and define your models via a schema.
