title: Creating multiple subs on same topic to implement load sharing (pub/sub)
body: <p>I spent almost a day on google pub sub documentation to create a small app. I am thinking of switching from rabbitMQ to google pub/sub. Here is my question:</p>
  
  <p>I have an app that push messages to a topic (T). I wanted to do load sharing via subscribers. So I created 3 subscribers to T. I have kept the name of all 3 subs same (S), so that I don't get same message 3 times.</p>
  
  <p>I have 2 issues:</p>
  
  <ol>
  <li>There is no where I console I see 3 same subscribers to T. It shows 1</li>
  <li>If I try to start all 3 instances of subscribers at same time. I get "A service error has occurred.". Error disappeared if I start in sequential manner.</li>
  </ol>
  
  <p>Lastly, Is google serious about pub/sub ? Looking at the documentations and public participations, I am not sure if I should switch to google pub/sub.</p>
  
  <p>Thanks,</p>
