title: Does Flask Rate Limiter work with Elasticache (Redis 2.8)?
body: <p>My large-scale web application currently uses Python Flask rate-limiter. I have several Amazon EC2 instances running the application. And the Flask rate-limiter relies on Redis instances I have setup. I'm using Redis 3.0.</p>
  
  <p>I'm interested in replacing my Redis instances with <a href="https://aws.amazon.com/elasticache/redis/" rel="nofollow">Amazon Elasticache For Redis</a>. Elasticache supports Redis 2.8. So I will be downgrading from Redis 3.0.</p>
  
  <p>Does Flask rate-limiter use any features found in Redis 3.0 that are not found in Redis 2.8? If not, I should not run into any trouble. But the Flask Rate-limiter <a href="https://flask-limiter.readthedocs.io/en/stable/" rel="nofollow">documentation</a> doesn't say what version of Redis it requires/uses.</p>
