Remove Item in DynamoDB Using Java (Guide w/ Code Examples)

To delete an item from a DynamoDB table using the AWS SDK for Java, you can use the deleteItem method of the AmazonDynamoDBClient class. This method enables you to delete an item from a table using its primary key values.

import java.util.Map;
import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClient;
import com.amazonaws.services.dynamodbv2.model.AttributeValue;
import com.amazonaws.services.dynamodbv2.model.DeleteItemRequest;

// Replace "tableName" with the name of your DynamoDB table
String tableName = "tableName";

// Create a DynamoDB client
AmazonDynamoDBClient client = new AmazonDynamoDBClient();

// Define the primary key values for the item you want to delete
Map<String, AttributeValue> key = Map.of(
    "id", new AttributeValue().withN("123"),  // primary key attribute"type", new AttributeValue().withS("foo")  // sort key attribute
);

// Create a request to delete the item
DeleteItemRequest request = new DeleteItemRequest()
    .withTableName(tableName)
    .withKey(key);

// Delete the item from the table
client.deleteItem(request);
