Let's understand how to get multiple items from the DynamoDB table using the AWS SDK for Java.
Let's try to understand how to get multiple stored items from the DynamoDB table using Java:
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);
Create an instance of the
TableKeyAndAttributes
class, and add theprimary
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");
