Looking for a deeper understanding (unable to post to ) about rdsn

@bswtzr, thx for the interest. Since we want to control all the non-determinism, we need to ensure all application logic running in rDSN controlled threads. As for the issue u raised, we have been considering automatically starting a default app to run them instead of asking developers to issue an explicit dsn-mimic-app. That work item is in the list. If you are interested, welcome to contribute the implementation(pull request to imzhenyu/rdsn for auto-test and latest version), or if u think it stops your further work, let us know and we will prioritize the item and finish it in short time.

Multiple replicated apps can run in the same assembly. What's missing now is a command to meta server to register multiple apps. Replication server already supports this.

@bswtzr, we now have the solution done for your problem. Please check at imzhenyu#33 . It is not yet merged into Microsoft/rDSN, but you can get it from imzhenyu/rDSN for the time being.

@imzhenyu I was hoping to spend more time here but got involved in other work. I've attached a simple app built with your latest rdsn code that calls server-r from server-nr as detailed in my initial post. server_r is a badly ported counter_service from your tutorial but good enough for this purpose. Entering add/read commands from the console usually results in a timeout using nativerun or fastrun but the simulator works ok. Maybe I doing something wrong? You'll need to avoid stepping into the code...a debugger side-effect allows it to run properly.

@imzhenyu, I was able to get this working by using the [replication] settings from simple_kv. I've attached the latest code as I also updated counter_server_impl to match simple_kv.server.impl.

Thanks @bswtzr You may want to submit a pull request for updating counter_server_impl if you want:)
