Getting ready

To perform this operation, you can use the IDE of your choice.

How to do it

Let's try to understand how to get multiple stored items from the DynamoDB table using Java:

1. Create an instance of the DynamoDB class and initialize it with the desired AWS region and credentials:

   AmazonDynamoDBClient client = new AmazonDynamoDBClient(new ProfileCredentialsProvider());
   client.setRegion(Region.getRegion(Regions.US_EAST_1));
   DynamoDB dynamoDB = new DynamoDB(client);

2. Create an instance of the TableKeyAndAttributes class, and add the primary key details of the items you wish to retrieve using in one go:

   TableKeysAndAttributes productKeysAndAttributes = new TableKeysAndAttributes("productTable");
   productKeysAndAttributes.addHashAndRangePrimaryKey("id", 10, "type", "phone");
   productKeysAndAttributes.addHashAndRangePrimaryKey("id", 20, "type", "phone");
