scala - How does Akka 2.4.x work in A Cluster Application when I loose one of my nodes -


my application has set of actors, each 1 doing heavy computation, , each 1 executing different business logic. @ end each actor sends result supervisor in turn persist data.

my intention have them distribute in 3 nodes split/balance workload, make system high available, allowing on of machines "die".

  • there no need share state among machines

how akka solve scenario?

is akka cluster need?

are there examples fall in domain?

to share state between instance can use sharding , persistentactor. can play reactive missile defend project visualise happened if node goes down.

there nice talks on jdd2015 sharding akka. theory production , scala exchange - beat aliens akka cluster showing how use distributed actors (with cluster , sharding) , how behave in situation of turning off 1 of nodes.
