akka-crashcourse

Project for getting a feeling of Akka for a small group of engineers

Basic idea is to together develop a game server that hosts games of Battleship. As a sarting point, the game logic is provided.

TODO before starting:

It is up to the engineers to:

(Reactive principles) rewrite some of the game logic to reactive, using asynchronuous message passing
(Akka-http) implement an http api based on akka-http
(CQRS / Sharding / Persistence) implement event sourcing for the gamestate (incl refactoring of gamestate to suit event sourcing)
(Actor design) implement a distributed version of placeBoats, every boat being an actor and finding their own way on the battlefield
- (Timeouts, supervision) When one of the boat actors does not respond, manage this
(Routing / Scaling) use routing actor to let multiple random players play the game (these have bad performance)
(Akka FSM) Creating a new game should be in iterative process: first the players are chosen, then (optionally) the size of the grid and the types of boats are defined, and then the game can be started
(Akka FSM) The Game actor has states in which it is waiting for a player, this can be done using Akka FSM
(Gatling) We need a performance test to finetune the implemented features
(Streams) - replayen/spectaten van games, data analyse op games, misschien score-/ladder-/mostactive-dashboardgeneratie oid?
(Replicated Data) - Maintain a list of all players in the game and how much they've won/lost
