title: Google App Engine - design considerations about cron tasks
body: <p>I'm developing software using the Google App Engine. </p>
  
  <p>I have some considerations about the optimal design regarding the following issue: I need to create and save snapshots of some entities at regular intervals.</p>
  
  <p>In the conventional relational db world, I would create db jobs which would insert new summary records.</p>
  
  <p>For example, a job would insert a record for every active user that would contain his current score to the "userrank" table, say, every hour.</p>
  
  <p>I'd like to know what's the best method to achieve this in Google App Engine. I know that there is the Cron service, but does it allow us to execute jobs which will insert/update thousands of records?</p>
