AWS DynamoDB trigger using Lambda in JAVA

Question

I am trying to trigger an AWS lambda function written in Java, on dynamodb stream events. Amazon has a guide for the same, using NodeJS here http://docs.aws.amazon.com/lambd

Answer 1

Your code caused the following exception in CloudWatch log,

Class does not implement an appropriate handler interface....

Once I changed the code to the following, I can get the SNS message just fine.

public class RecomFunction implements RequestHandler {

    public Void handleRequest(SNSEvent event, Context context) {

        ...
        return null;
    }

}
