@nvivo
not easy to do that
Aaron Stannard
@Aaronontheweb
going to see if I can update our VM image for @Horusiath
so we can unit test the SQL-server Akka.Persistence Impl
Natan Vivo
@nvivo
ok.. and I'll go watch a movie
9pm here... time to stop
Aaron Stannard
@Aaronontheweb
haha
Natan Vivo
@nvivo
aaron, are you married?
does that answer your question?
Natan Vivo
@nvivo
hahahaha
that's why you have so much energy then!
Aaron Stannard
@Aaronontheweb
haha

I now know more about the XUnit inner working than I ever wanted to know.
Aaron Stannard
@Aaronontheweb
@annymsMthd if you stick around on Akka.NET long enough you'll use that sentence for a lot of different things
oh hey, here's how the JVM type system does X!
:P
Joshua Benjamin
@annymsMthd

@smalldave Did you see @Aaronontheweb and my conversation about the MultiNodeTestRunner this morning?
Nikita Tsukanov
@kekekeks

and small examples do fit nicely in the comments - we do that in a few places

Oh, yeah, I remember that ReSharper tooltip that covered almost entire 27" screen with example from Xamarin.Forms while I was typing.

SQL-server Akka.Persistence Impl

I'm wondering, why the code is so MSSQL-specific. It was easy just to use something lightweight like linq2db and get support for almost all database engines.

@kekekeks
Is there any way for an actor to have "wildcard" address? I. e. I want to have some EntityLazyLoaderActor to recieve all messages to /user/entities/* and then load an actor from persistent storage if it's not already in the memory
Natan Vivo
@nvivo
I think you can do exactly that with actorselection to send messsages. But Akka cannot start actors by itself only by the path
Nikita Tsukanov
@kekekeks

can do exactly that with actorselection

Nope, ActorSelection does exactly the opposite

Natan Vivo
@nvivo
?
Roger Johansson
@rogeralsing
ah you want to "intercept" the path and then start actors that arent started, right?
Natan Vivo
@nvivo
Exactly that = use /path/to/manyactors/*
Nikita Tsukanov
@kekekeks
Yup
Roger Johansson
@rogeralsing
like a proxy
Nikita Tsukanov
@kekekeks
exactly
If you have, like, 1KK entities it would take a lot of time to load them from the storage
Roger Johansson
@rogeralsing
imo, easiest way, make a proxy that acts like the consistent hash router. but with the ability to start actors also
all messages goes to the same actor, and then use a property of the messages to identify what child to route to
Natan Vivo
@nvivo
This looks like the concept from orleans right?
Nikita Tsukanov
@kekekeks
So I'm stuck with old pattern of having ISmthManager that asks you for an id of that something in every call
meh
Quite kills the idea of just passing ActorRef around
Natan Vivo
@nvivo
I think you can do that with rogers idea
Ask a single actor for a message that contains an actorref
Let that single actor give you the reference somehow
Nikita Tsukanov
@kekekeks
And then be unable to unload that actor after inactivity timeout
but might just work in most cases
Since having an actor is cheap anyway
Natan Vivo
@nvivo
You can unload with SetTimeout and watch in the parent
Roger Johansson
@rogeralsing
Akka does not support the concept of virtual actors, we follow the JVM impl, they are looking into that on their side.. but as of now, there is no "on demand" activation of actors
Nikita Tsukanov
@kekekeks
Yup. Ask the parent for the reference, timeout expired, actor died, ActorRef is void
So these "ondemand" actors should live forever
Is it actually a good idea to have an actor for every entity in the system?
Natan Vivo
@nvivo
This is the orleans concept, akka is different. But both can achieve similar results. Looks like you want a specific solution, not a specific goal
Nikita Tsukanov
@kekekeks
Or just go with instances of UserManagerActor routed via consistent hash
Roger Johansson
@rogeralsing
depends on its responsibillities, if the actor is a heart beat creator for a heart machine, i'd say yes :) if it's a business entity / aggregate root, then no
