title: Firebase Functions - Do something every 10 minutes
body: <p>I'm building an app using Firebase. There's an admin setting I want to build, that essentially populates one of my nodes with data. It would do this every 10 minutes, and there are 50-80 data points that I'd want to add. </p>
  
  <p>So this would take roughly 13 hours total, I'd probably want to expand this though in the future. I would only call this function, maybe once a week. </p>
  
  <p>I would simply do this using a <code>setTimeout</code> but I've heard this can be expensive? Does someone know roughly how expensive this would be?</p>
  
  <p>I'm not that experienced with CRON jobs, is there a better way of doing this with Firebase? It's not something I want to have running constantly, and it's not at a specific time, but just whenever I need it. I'd also potentially want to have the job running multiple times, at the same time. Which seems to be super easy using <code>Firebase Functions</code>.</p>
  
  <p>Any ideas? Thank you!</p>
