Examples of several akka use cases/patterns

Akka Cluster + Group Routing

Running

There are a few ways to run the application. You can start by running the following:

sbt "runMain com.example.Application"

Once you have this running, the cluster will be up with a parent actor (as a singleton) and several worker actors. To see work submit to this system, add a client to the cluster in a new terminal:

sbt "runMain com.example.ClientMain"

If you would like to see more interesting behavior, run the following commands. Each command should be in a new terminal window:

sbt "runMain com.example.Application 2551"
sbt "runMain com.example.Application 2552"
sbt "runMain com.example.Application 0"
sbt "runMain com.example.WorkerMain"
sbt "runMain com.example.ClientMain"

The three terminals that ran Application will all have the actor singleton, and a worker. You can terminate 2551, and see the singleton move to another cluster member with the "parent" role.

Tests

To test this application, you will need to run the following command:

sbt multi-jvm:test

Test Structure

This project uses the SBT multi-jvm plugin. Tests are all in src/main/multi-jvm/scala. ApplicationTest contains the tests that will be executed by this command.
