title: Redis HA without clustering
body: <p>I tried to find more info about it online, but cant seem to find a fitting answer.</p>
  
  <p>Our new application uses HA loadbalancers  on top to distribute visitors to clustered ampq and clustered mysql and everything works flawlessly.</p>
  
  <p>Now we have decided that we need to store our sessions on REDIS and according to everyone out there.. REDIS seems to be a good choice.</p>
  
  <p>But what I dont understand is, since Redis doesnt support cluster yet in production. How do people achieve HA with Redis?  Its all great to setup a Master-Slave REDIS setup, but that means I can only write to the master. What happens if the master die? And even with Redis Sentinel promoting slaves to master.. the replication from master to slave can have a delay and reply me with stale data. How do people prevent that?</p>
  
  <p>But to keep it short, I just dont "see" it. Please enlightenment me!  Thank you</p>
