Passing Contextual Information

阅读更多关于 Passing Contextual Information

问题 We are in the process of adding akka.net actors to part of a legacy system. The basic idea is that a message comes in from an external system, it is handed off to a logic that is managed by akka.net actors which then talk to legacy components that do things like save data to the database. The legacy code relies on the fact that a userId is set in the CallContext, which it can then retrieve before doing database writes (to store things like "CreatedBy" and "LastModifiedBy"). It seems clear

《西游记》中真假美猴王让人着实难以区分，但是我们熟知了其中的细节也不难把他们剥去表象分别出来。对问题不太关心的可以直接调到文中关于 .Net文件版本的介绍问题最近在编译AKKA.net 时出现了一个问题： Newtonsoft.Json.dll 冲突.

阅读更多关于 Getting Akka.NET to connect to a remote addresses

问题 All the demos I have found showing how to get started with remoting in Akka.NET demonstrate the simplest use case where the two actors are running on the same machine using localhost. I am trying to get an Akka.NET actor to connect to a remote machine and have run into some difficulty. The code is extremely simple: Client Code : var config = ConfigurationFactory.ParseString(@" akka { log-config-on-start = on stdout-loglevel = DEBUG loglevel = DEBUG actor { provider = ""Akka.Remote

Can I Read/Write from separate actors with same PersistenceId?

阅读更多关于 Can I Read/Write from separate actors with same PersistenceId?

问题 The Petabridge blog's Akka.Persistence intro makes it clear that you can't have multiple actors with the same PersistenceId: The PersistenceId field is important - it uniquely identifies an entity that is persisting its state using Akka.Persistence, and there should be exactly one persistent actor at any given time for a single PersistenceId . [...] so imagine if you have two actors with the same PersistenceId but different sequence numbers writing to the same store. It will be chaos and will
