* reduce allocations with specialized ImmutableLongMap
* backed by arrays, allocation free lookups with binary search
* use it for UID -> Association Map
* pass Association in InboundEnvelope to reduce to only
one lookup per incoming message
* use ImmutableLongMap instead of the QuarantinedUIDSet
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.
