// Submit create table request to client
CreateTableResult result =
dynamoDBClient.createTable(request);
Once the request is submitted, DynamoDB takes a couple of minutes to get the table ac-
tivated; meanwhile, the SDK provides an API to wait:
Tables.waitForTableToBecomeActive(dynamoDBClient, "Book");
Once the table is activated, you can continue with further execution.
