title: Google App Engine HRD - what if I exceed the 1 write per second limit for writing to the entity group?
body: <p>According to the Google App Engine documentation, writing to one entity group is limited to one write per second when using High Replication Datastore. So...</p>
  
  <ol>
  <li>What happens if I exceed this limit? Some kind of exception? And what should I do?</li>
  <li>How do I know that I'm close to exceeding this limit? I can design the application in a way that particular actions (adding an entity...) are not likely to happen often but naturally I can't guarantee that.</li>
  </ol>
