title: Can I trigger a subscription event in AWS AppSync from my lambda function?
body: <p>As the title says I want to trigger a subscription event from my code.</p>
  
  <p>Think about an use case, where a user wants to search the Internet for the cheapest flight. A Lambda function starts scraping popular flight tickets offering websites and with each find it sends a subscription event to an app. Is this case possible to be hosted with AppSync?</p>
