Patrik Nordwall 3f73705abc Use consistent hash to heartbeat to a few nodes instead of all, see #2284 
* Previously heartbeat messages was sent to all other members, i.e.
  each member was monitored by all other members in the cluster.
* This was the number one know scalability bottleneck, due to the
  number of interconnections.
* Limit sending of heartbeats to a few (5) members. Select and
  re-balance with consistent hashing algorithm when new members
  are added or removed.
* Send a few EndHeartbeat when ending send of Heartbeat messages.

h1. Akka

We believe that writing correct concurrent, fault-tolerant and scalable 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 together with Software Transactional Memory we raise the abstraction level and provide a better platform to build correct concurrent and scalable applications.

For fault-tolerance 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.
