[akka-user] Sharded actors sending messages into other shard regions

2017-06-29 Thread Richard Ney
I have an application with 3 different shard regions the maintain various State Machine actors based on events from a data stream. Some of the events received by the system require a specific actor type to verify the validity of the event or based on state send events to actors of a different

Correct, I'm talking about JVM's. Today we use 2 JVM's per machine (for actor hot backup). Thanks. El jueves, 29 de junio de 2017, 21:18:13 (UTC+2), Patrik Nordwall escribió: > > Are we talking about the same thing. When we say nodes we mean JVMs > (ActorSystem instances) and typically you

Are we talking about the same thing. When we say nodes we mean JVMs (ActorSystem instances) and typically you would run one or a few JVMs on one machine (EC2/GCE instance). Do you mean nodes in that sense, or do you mean actors? On Thu, Jun 29, 2017 at 8:15 PM, Eduardo Fernandes

Hi again. I'm talking about multiple data-centers, so reducing the chattiness will be very welcome. The logic unit question is a bit open yet from our side. We're considering different scenarios. I can talk to you more privately later. Anyway, do you consider that numbers from 20.000 to

Are those in different data centers or one? We’re also working on multi-dc features, which limit the chatty-ness between datacenters, allowing for even greater scalability. The interesting question to ask if they are indeed one logical unit and clustering them all indeed is the thing to do or

Hi Konrad. Thanks for the quick answer. We're managing from 20.000 up to 50.000 nodes with 8 to 16 Gigs of RAM. In fact we could adapt the architecture depending of Akka capacity but the upper limiter in a cluster could oblige us to develop a kind of inter-cluster communication channel or

We’re currently preparing for such large-scale scalability test on the new remoting. How many nodes are you expecting more or less from memory per user estimates etc? — Konrad On 30 June 2017 at 02:43:43, Eduardo Fernandes (edu...@gmail.com) wrote: Hi all. I'm starting a new project and I'm

Hi all. I'm starting a new project and I'm wondering about what is the recommended max number of nodes in an Akka cluster. I've read numbers around 2400 in this test but with the new Artery
