title: Does Kie execution server (Or Drools server)support High Availability?
body: <p>I'm newbie to Drools. For powerful drools fusion or timer based rule, most of them are stateful. So, an obvious issue is coming: if the server of the stateful session is down, is that possible to recover the session by Kie execution server?</p>
  
  <p>For example, I start a timer(int:30s) rule, but the server that hosts the ksession is down after 15s. How to recover it?</p>
  
  <p>I've read some of the blogs like:</p>

  <p>I've also read a little bit about the VFS Clustering in official doc. But I'm still confused about is there an easy way to achieve my case?</p>
  
  <p>Thanks,</p>
