title: Polling vs subscriptions in Apollo Client?
body: <p>Im making a social website. When any user updates or creates new content on the site I need any other users viewing the site to see the change update. </p>
  
  <p>I have comments which requite low latency so a subscription is recommended for this. </p>
  
  <p>I also have events but these don't need such a low latency. Updating every 10 seconds would be fine. Should I also user subscriptions for this or would polling be less expensive for the server? </p>
