Discussion

• How would you test this?

Tests are in ./tests folder. See below how to run them.

• What would you do if you were told this needs to handle 1 million players?

1. Integrate a proven REST framework (i.e. Django REST / Tastypie) to get caching, authentication, pagination, ...
2. Run the service on a number of Apache instances behind a load balancer
3. Use a (possibly NoSQL) distributed database that allows masterless replication (Cassandra).
4. Monitor the load
5. Alternatively, I'd consider Erlang-based stack with CouchDB and Yaws :)
