title: App Engine: What are the Default Retry Parameters for Failed Taskqueues
body: <p>Google App Engine has a robust set parameters to automatically retry failed tasks in the distributed tasksqueue. While the <a href="https://cloud.google.com/appengine/docs/python/config/queue?hl=en#retry_parameters" rel="nofollow">documentation explains what these parameters do</a>, it fails to specify what the default parameters are. </p>
  
  <p>What are the defaults for the Taskqueue's retry parameters. More specifically, what are the default values for the following retry parameters:</p>
  
  <ul>
  <li><code>task_retry_limit</code></li>
  <li><code>task_age_limit</code></li>
  <li><code>min_backoff_seconds</code></li>
  <li><code>max_backoff_seconds</code></li>
  <li><code>max_doublings</code></li>
  </ul>
