Cluster does have a more fine-grained approach where there is an Unreachable state which is recoverable. Yes, Quarantine does happen in cluster, things that have been removed cannot come back. > > I'm asking because I'm considering using akka-remoting as a point-to-point > RPC layer, in a codebase that doesn't use actors, where the Cluster would > be inappropriate. > Quarantine basically exists to prevent inconsistent state where actors on the other system are reported dead and then would suddenly come back after a network split. Instead the system is isolated as soon as it has been considered dead. If you don't use deathwach or remote deployment there won't be Quarantine. That said, even if you use above features you can set a very lenient failure detector. For example if your system Quarantines the other one after 1 hour of heartbeat silence then you have *much worse* problems than the Quarantine state. -Endre > > Thanks, > > Daniel Armak > > On Wed, Feb 24, 2016 at 6:55 PM, Konrad Malawski <kt...@lightbend.com> > wrote: > >> Yeah, for example if irrecoverable loss of system messages happens. >> In general death watch on Actors using remoting can in failure scenarios >> (see above) lead to a Quarantine. >> >> Note that Quarantine is irrecoverable, unlike "Unreachable" which is used >> in the Cluster. >> Short answer: Use the Cluster – it's more resilient. >> >> -- >> Cheers, >> Konrad 'ktoso’ Malawski >> <http://akka.io>Akka <http://akka.io> @ Lightbend <http://typesafe.com> >> <http://lightbend.com> >> >> On 24 February 2016 at 17:53:16, Daniel Armak (danar...@gmail.com) wrote: >> >> Hi, >> >> If I use akka-remoting (not cluster), and I don't send any >> PossiblyHarmful messages (so no remote actor creation or watching), can the >> association ever be quarantined? >> >> Thanks, >> >> -- >> Daniel Armak >> -- >> >>>>>>>>>> Read the docs: http://akka.io/docs/ >> >>>>>>>>>> Check the FAQ: >> http://doc.akka.io/docs/akka/current/additional/faq.html >> >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user >> --- >> You received this message because you are subscribed to the Google Groups >> "Akka User List" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to akka-user+unsubscr...@googlegroups.com. >> To post to this group, send email to akka-user@googlegroups.com. >> Visit this group at https://groups.google.com/group/akka-user. >> For more options, visit https://groups.google.com/d/optout. >> >> > -- > >>>>>>>>>> Read the docs: http://akka.io/docs/ > >>>>>>>>>> Check the FAQ: > http://doc.akka.io/docs/akka/current/additional/faq.html > >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user > --- > You received this message because you are subscribed to the Google Groups > "Akka User List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to akka-user+unsubscr...@googlegroups.com. > To post to this group, send email to akka-user@googlegroups.com. > Visit this group at https://groups.google.com/group/akka-user. > For more options, visit https://groups.google.com/d/optout. > -- Akka Team Typesafe - Reactive apps on the JVM Blog: letitcrash.com Twitter: @akkateam -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
