Agents or actors?

Nicolas Bourbaki

@b0urb4k1

actors sorry

I was thinking if they are lightweight enough to use them for agents in a multi agent system.

I would assume though that if you would like to do that you would write your own dispatcher for it.

Andreas Dirnberger

@Zetanova

not big, i little bigger then a normal object, plus some registration in lists

yes, the are very light in this sence

over a count of 100k you would need to think about memory

Nicolas Bourbaki

@b0urb4k1

Ok :)

Andreas Dirnberger

@Zetanova

but i dont know the exact byte count for each in avg.

i am loading ~1000 per each aggregate root type

and the app has still low memory consumation

messages are short lived and most likly removed on Gen0 GC

Nicolas Bourbaki

@b0urb4k1

Are there any multi agent systems that use Akka.net?

Andreas Dirnberger

@Zetanova

multi tenant?

Andreas Dirnberger

@Zetanova

yes, akka.net is perfect for it

Nicolas Bourbaki

@b0urb4k1

But you have shared state in form of the world state.

Andreas Dirnberger

@Zetanova

or an other actor-model system

world => actor

can be a singleton service t0o, but better an actor

Nicolas Bourbaki

@b0urb4k1

Ok but i guess you need to throw away determinism then.

Andreas Dirnberger

@Zetanova

not realy

Nicolas Bourbaki

@b0urb4k1

Lets say you wanted to model something like a board game.

Then you need the sequence of actions of several of the actors.

Andreas Dirnberger

@Zetanova

then the board can sync the steps or a child of board-actor

Nicolas Bourbaki

@b0urb4k1

Oh!

What is the name of the class i need to look up?

Andreas Dirnberger

@Zetanova

ActorBase

If I send a RoundRobin router a PoisonPill.Instance i assume they all get the PoisonPill?

Christian Duhard

@cduhard

are there any examples on how to use GracefulStop correctly?

Aaron Stannard

@Aaronontheweb

@cduhard if you PoisonPill the router the router dies

and so do all of its routees

if it's a pool router

Christian Duhard

@cduhard

k it is

Aaron Stannard

@Aaronontheweb

for using GracefulStop

how that works by default is it PoisonPill's the target actor

Christian Duhard

@cduhard

@Aaronontheweb i am mostly not sure what to do with the Tasks if I have numerous children to stop

Aaron Stannard

@Aaronontheweb

and you the Task<bool> returns true if the temporary actor created by the GracefulStop call, kind of like the temporary actors created by Ask, gets a Terminated message

Christian Duhard

@cduhard

say for instance I have

Actor2.GracefulStop(TimeSpan.FromSeconds(10));
Actor3.GracefulStop(TimeSpan.FromSeconds(10), new Shutdown());

when all gracefulstop Tasks are complete I need to send a Passivate type message

i guess this is more about my shitty async skills than anythig

Christian Duhard

@cduhard

I assume sending a poisonPill just effects that actor and not it's watched children

Aaron Stannard

@Aaronontheweb

@alexvaluyskiy that's the goal

Christian Duhard

@cduhard

@Aaronontheweb so the bool returned from GracefulStop just tells me if the stop was actually graceful and didn't time out?

Aaron Stannard

@Aaronontheweb

bool == false if it timed out

didn't shut down in time

bool == true if it did

Christian Duhard

@cduhard

so its still running if it's false?
