title: How to estimate how large a redis database will be?
body: <p>I'm trying to decide what size Redis To Go option to go for in heroku.</p>
  
  <p>Say that I want to keep about a million records in Redis for easy access. </p>
  
  <p>If each record is about 1-10kb in size, does this mean that the entire database will be 1,000,000 * 1-10kb or is there some hidden overhead that I don't know about?</p>
