title: Scheduling MapReduce jobs for MongoDB
body: <p>This is more of an implementation question, but are there any shortcomings to using something simple like cron to schedule tasks like mapreduce for MongoDB? Say something needs to be executed every hour, it seems like a suitable way to do this... But I guess I'm just asking because of all the popular job queuing systems out there like Resque and others.</p>
  
  <p>I suppose my question is more like, does cron provide solid and reliable enough solution? Thoughts?</p>
