title: Schedule push notification in lambda aws at regular interval
body: <p>I want to trigger a push notification from the backend at regular intervals. What is the best way to do that? I am thinking to have a cron expression that I will schedule for every minute. I am working on stock app and I need to send a notification to the user about the stock rising or declining. I have integrated frontend &amp; backend with a notification that is a trigger from the client-side. But I need to trigger it from backend without client-side being triggering it every second as it will affect performance.</p>
  <p>My applications are in react, node, and AWS lambda.</p>
