java - Good use case for Akka -
i have heard lots of raving akka framework (java/scala service platform), far have not seen many actual examples of use cases for. interested in hearing things developers have used succesfully.
only 1 limitation: please not include case of writing chat server. (why? since has been overused example lots of similar things)
i have used far in 2 real projects successfully. both in near real-time traffic information field (traffic in cars on highways), distributed on several nodes, integrating messages between several parties, reliable backend systems. i'm not @ liberty give specifics on clients yet, when ok maybe can added reference.
akka has pulled through on projects, though started when on version 0.7. (we using scala way)
one of big advantages ease @ can compose system out of actors , messages no boilerplating, scales extremely without complexities of hand-rolled threading , asynchronous message passing between objects free.
it in modeling type of asynchronous message handling. prefer write type of (web) services system in style other style. (have ever tried write asynchronous web service (server side) jax-ws? that's lot of plumbing). system not want hang on 1 of components because implicitly called using synchronous methods, , 1 component locking on something. stable , let-it-crash + supervisor solution failure works well. easy setup programmatically , not hard unit test.
then there excellent add-on modules. camel module plugs in akka , enables such easy development of asynchronous services configurable endpoints.
i'm happy framework , becoming defacto standard connected systems build.
