* CoordinatedShutdown that can run tasks for configured phases in order (DAG) * coordinate handover/shutdown of singleton with cluster exiting/shutdown * phase config obj with depends-on list * integrate graceful leaving of sharding in coordinated shutdown * add timeout and recover * add some missing artery ports to tests * leave via CoordinatedShutdown.run * optionally exit-jvm in last phase * run via jvm shutdown hook * send ExitingConfirmed to leader before shutdown of Exiting to not have to wait for failure detector to mark it as unreachable before removing * the unreachable signal is still kept as a safe guard if message is lost or leader dies * PhaseClusterExiting vs MemberExited in ClusterSingletonManager * terminate ActorSystem when cluster shutdown (via Down) * add more predefined and custom phases * reference documentation * migration guide * problem when the leader order was sys2, sys1, sys3, then sys3 could not perform it's duties and move Leving sys1 to Exiting because it was observing sys1 as unreachable * exclude Leaving with exitingConfirmed from convergence condidtion |

Akka
We believe that writing correct concurrent & distributed, resilient and elastic applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction.
Akka is here to change that.
Using the Actor Model we raise the abstraction level and provide a better platform to build correct concurrent and scalable applications. This model is a perfect match for the principles laid out in the Reactive Manifesto.
For resilience we adopt the "Let it crash" model which the telecom industry has used with great success to build applications that self-heal and systems that never stop.
Actors also provide the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications.
