title: How do I implement "write-behind" in a StatefulActor
body: <p><a href="https://azure.microsoft.com/en-us/documentation/articles/service-fabric-reliable-actors-pattern-smart-cache/" rel="nofollow">Azure Service Fabric documentation</a> says that:</p>
  
  <blockquote>
    <p>Actors provide flexibility for the developer to define rich object
    structures as part of the actors or reference object graphs outside of
    the actors. In caching terms actors can write-behind or write-through,
    or we can use different techniques at a member variable granularity.</p>
  </blockquote>
  
  <p>In terms of a <code>StatefulActor</code> or <code>StatefulActor&lt;T&gt;</code>, how would one go about implementing write-behind to improve throughput of state-changing methods?</p>
