[akka-user] Example for change in 2.0-M1 stream

Hello, I have a "switch" code shown below in Akka stream 1.0. I'll be totally honest, I don't understand 100% of what's going on here--I reworked it from a sample found someplace. Is there an example somewhere of what an equivalent structure would look like in 2.0-M1? Thanks for any hints!

Hi André, Thanks for your reply, using Mapper works fine (a bit more verbose than the scala implementation) For those who have the same issue: here is the solution: private Future handleGetTask(RequestContext ctx){ return Patterns.ask(actorSystem.actorFor("myActor"), buildMessage(), 1000)

[akka-user] Re: Cluster Sharding - watching for termination of sharded actors.

Hi, I have done some deeper digging into that and it seems that the issue is not the Terminated message not being received. The sharded actor keeps running on both nodes of the cluster! The shard region correctly resolves where to send message so it's hard to spot this as long as you're using

[akka-user] Cluster Sharding Proxy vs Cluster Client

Brice, Thanks for the answer. I will definitely have a look into what the events could give me and how the strategy could be tuned to provide such events. tnks, Rod On Thursday, November 12, 2015 at 4:24:27 PM UTC, Brice Figureau wrote: > > On Thu, 2015-11-12 at 07:41 -0800, Rodrigo Boavida
