title: Estimating and measuring CloudKit database usage
body: <p>CloudKit has some pretty stringent <a href="https://developer.apple.com/icloud/documentation/cloudkit-storage/" rel="nofollow">data limits</a>, restricting to 50MB of database storage plus 1MB per user, with 250KB/day in database bandwidth plus 5KB per user.</p>
  
  <p>To find out how CloudKit incorporates database structure and protocol overheads into these numbers, is there a dashboard I'm able to look at to see the size of a record or table, or the amount of bandwidth consumed?</p>
