AWS Lambda - How to stop retries when there is a failure

Question

I know that when a Lambda function fails (for example when there is a time out), it tries to run the function 3 more times again. Is there any way to avoid this behavior? I\

Answer 1

I achieved this by placing the following line of code:

callback(null, "message");

Into my function such as the below update to DynamoDB. When there is an error, rather than retrying for hours on end, this callback outside of the if / else will stop the retries.

dynamodb.updateItem(params, function(err, data){
                 if (err) {
                    console.log(err)
                    callback(err, data)
            } else {
                 console.log(data);
                 callback(null, data);
           }
           callback(null, "message");
        });
