Sample Project for Akka Cluster with Persistence

Intended to demonstrate a working project with Akka Clusters and Persistence.

Implemented a sharded counter.

• Given three nodes Node 1, 2, and 3
• And three counters C1, C2, and C3 located in the node of the same number
• When there's a request in (Node 3) to increment counter (C1)
• Then (Node 3) should forward the processing to (Node 1)

To test:

• Run three processes

$ sbt "runMain com.rmpader.gitprojects.MainApp1"

$ sbt "runMain com.rmpader.gitprojects.MainApp2"

$ sbt "runMain com.rmpader.gitprojects.MainApp3"

• Send a cURL to the three servers for varying counters

$ curl http://localhost:8081/count/1
$ curl http://localhost:8081/count/2
$ curl http://localhost:8081/count/3

$ curl http://localhost:8082/count/1
$ curl http://localhost:8082/count/2
$ curl http://localhost:8082/count/3

$ curl http://localhost:8083/count/1
$ curl http://localhost:8083/count/2
$ curl http://localhost:8083/count/3
