title: Azure Service Fabric actor reminder update?
body: <p>Suppose I have a reliable actor that registers a reminder in <code>OnActivateAsync</code>. This reminder has a <code>period</code> that is retrieved from some persistent storage. After some time the actor is garbage-collected.</p>
  
  <p>After some more time the actor is called or the reminder fires and <code>OnActivateAsync</code> is called by the runtime. In the meantime, I updated the reminder <code>period</code> in persistent storage.</p>
  
  <p>What happens now? I attempt to register the reminder again but with a different <code>period</code>. Will the reminder be updated with the new <code>period</code>?</p>
  
  <p>Another case is an update of the actor. Suppose the <code>period</code> is hard-coded but a new version of the actor uses a different <code>period</code>. What happens now when <code>OnActivateAsync</code> is called and the reminder is registered again?</p>
