Batch Write Using DynamoDB Mapper (Guide w/ Code Examples)

Provided by Rafal Wilinski
With the batch write operations, you can save multiple items to the DynamoDB table, by passing a list of items to the batchSave
method of the DynamoDBMapper class. This method can be used to save new items and update existing items, depending on the primary key values provided. You might use the DynamoDBMapper's batchSave
method to write multiple items in a single request in Java.
import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapper; import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapperConfig; public class BatchWriteExample { public static void main(String[] args) { // Create a new DynamoDBMapper AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard().build(); DynamoDBMapper mapper = new DynamoDBMapper(client); // Define a list of items to write List<Product> items = new ArrayList<>(); items.add(new Product("111", "Product 1", 10, 2)); items.add(new Product("222", "Product 2", 20, 4)); items.add(new Product("333", "Product 3", 30, 6)); // Write the items mapper.batchSave(items, DynamoDBMapperConfig.DEFAULT); } }
