Nice work. Is it compatible with existing cluster-consul-provider? I'm working for a cluster-etcd-provider of protoactor-go, it's inspired by cluster-consul-provider.

@cupen It is conceptually the same, but some rewrites to handle some scenarios better. will bring these changes to Go also

Great library all round, I'm using the dotnet version and looking at the developments in grpc-dotnet I was wondering of the core developers had any thoughts on moving from the native wrapper version of grpc to grpc-dotnet ? This hints at some potential performance gains https://twitter.com/JamesNK/status/1290411721660592128

I found some examples of protoactor-go was broken. The import path was wrong https://github.com/AsynkronIT/protoactor-go/blob/dev/_examples/chat/server/main.go#L8.
I'll make a pr for it, if no one do the same thing.

Some examples got broken just because the import path was wrong, but there a one is because unknown reason, here is it. https://github.com/AsynkronIT/protoactor-go/tree/dev/_examples/remotessl

Hi there.
Long time no see but I have to dive in again within Proto.Actor stack, and just hit the Documentation & Bootcamp sections.
I would like to thanks @rogeralsing & the Proto.Actor community for this impressive work.
I discovered Proto.Actor 2 years ago, and at this time, it was not so newcomers-friendly ;), mainly due to lack of documentation.
Congratulations to everyone involved & keep up the good work. Impressive. Really.

Hi there, just found that AsynkronIT/protoactor-dotnet#542 within Proto.Remote.
Is it a known issue?

Hi. Could someone explain why I am getting this bug:

Hello folks. I would like to know whether there is a very elaborated tutorial in golang on how to implement an event sourcing behaviour. I have glanced through the doc and the example show very little in that regard.

Hi, just joined the forum, newbie in proto actor, a quick question: in proto actor, there is no actor path anymore (comparing to akka.net) then how to find the actors? or you have to know PID of an actor to interact with it?
beatsm
@beatsm
Just found the basecamp https://github.com/AsynkronIT/protoactor-bootcamp looks like a great learning resource but was wondering if anybody knows where the code for this is?
Milosz Krajewski
@MiloszKrajewski
@zhenlee-lt (disclaimer: I know nothing, I'm just exploring, like you). Seems like one way is with Clusters (RegisterKind, GetAsync), but if you are using only local actor system (no Remote, no Cluster) I actually found it hard to find actor by name. I don't think this is the way to do it, but it works for me:
If actor was spawned with context.SpawnNamed then you can find it with:
public static PID GetNamed(this IInfoContext context, string name)
{
    var pid = new PID("nonhost", name);
    _ = context.System.ProcessRegistry.Get(pid);
    return pid;
}
@rogeralsing @zhenlee-lt this most likely NOT the way to do it though

I'm getting the following error

2020/11/27 03:47:20 [REMOTE] Started EndpointWriter address="127.0.0.1:8090" 
2020/11/27 03:47:20 [REMOTE] EndpointWriter connecting address="127.0.0.1:8090"

2020/11/27 03:47:20 [REMOTE] EndpointWriter failed to connect address="127.0.0.1:8090" error="rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = \"transport: Error while dialing dial tcp 127.0.0.1:8090: connect: connection refused\""

What I did was :

  • Created a protoactor node on port 8091 (with a registered grain type A on it)
  • Created a protoactor node on port 8092 (with a registered grain type A on it)
  • Created a protoactor node on port 8090 (which creates 1000 grains of type A, 501 got created on 8091 and 499 on 8092)
  • Now I closed node 8091, and tried operating in the same 1000 grains again. A few grains got created on the still up node 8092 but 8090 (node operating with grains) stopped all of a sudden with get PID failed with StatusCode: 2
  • And 8092 is now continuously sending the error described very above

Now, I'm not able to understand why did get Pid failed, shouldn't it have known that the node is down and created the entity again. Another thing I didn't understand is why is 8092 still trying to reach to 8090 infinitely?

I would be really grateful if someone can help me

Hey!

Is there any way to wait for a message to complete without returning a value? Right now I'm just returning a bool and waiting for it, but it's getting quite annoying to write, I just want to run certain messages that modify the state on a sync way
