title: Can I use redis cache free edition in production for basic usages?
body: <p>I have a web application where I need to implement caching. I found Redis cache is open source and free to download. But I have also found it's limited for 15 days and after this limit I wont be able to change any configuration.</p>
  <p>While I need pretty basic key value pair only, I don't need to change any configuration at all. So, can I put the free version in production or it will raise an issue at later stage?</p>
