Port of Akka actors for .NET

I just stumble upon

Is Lighthouse mandatory to be used? What if I just deploy 5 nodes, 2 of which are seeds?
Aug 01 2018 11:10
No not mandatory, it's just so you have two well known nodes you can always and easily find
I guess that's where the comes from as well
Check the code, it is a cluster node, without any functional parts, except hosting an akkasystem.

It's not mandatory but we found it convenient for CI process - we always have our Lighthouses running, no need to redeploy them. And other components are updated all the time.
But didn't you experiment with Consul? You can even replace LH with your own discovery tools.

yes, we use Consul discovery on prod, but on a small (~10 nodes) cluster. When I tried to use it on a ~200 nodes cluster, there was an exceptions storm and I rolled back it quickly.
so if I were asked what problem I have with akka, I'd say - consul.

I am just not confident that the current solution can scale. not good. So I'm gonna try Lighthouse for the new project.
Must Lighthouse nodes be updated when I update akka packages?

AFAIK only when underlying comminication format changes.

dot netty was upgraded recently, 1.3.8 has a newer dotnetty, so I would recommend updating, if you are using 1.3.8 remote someplace, I would recommend upgrading.

lately every update to Akka contains some form of improvements to the cluster system. Which means that updating your lighthouse instances as well, is strongly recommended.

Hello everybody!!. I wonder if Akka is able to manage an overflow exception occurred in an actor. It closes the application and it does not execute the supervisor strategy.

would you like to describe this as an issue of github? It's a note worth tracking.

newer versions of NET don't allow catching StackOverflowException in a try-catch block. This is something you have to resolve outside Akka.
