通过回调从lambda获取响应并让lambda继续工作

exports.handler = (event, context, callback) => {
  lambda.invoke({
    FunctionName: 'longCheckout',
    InvocationType: 'Event',
    Payload: JSON.stringify(event, null, 2) // pass params
  }, function(error, data) {

    console.log(error, data)
    callback(null, data);
  });
};

exports.handler = (event, test, callback) => {
  docClient.update(params, function(err, data) {
    callback(....)
    // continue to execute 
  })
}
