title: A/B or canary deployments of Lightbend's Lagom with persistent entities?
body: <p>Is there a way to do A/B or canary deployments with Lagom Persistent Entities?</p>
  
  <p>I'm trying to plan out how we can build and deploy reactive microservices and I like the look of Lagom, but I can't see how we'd roll out new versions as canary or a/b testing releases. It seems like the stateful nature of the persistent entities would make that impossible? </p>
  
  <p>Assuming it's possible, I'd also like to figure out how to use Istio on Kubernetes to deploy and manage these new releases, so any pointers on that would be great. </p>
