Hi Diego,
apart from style questions (like using a sealed State trait instead of an
Int), there is just one thing: you might want to use `val` instead of `def`
when declaring the supervisorStrategy in general, unless you consciously
did it here because failure is so rare that the allocation should better
happen only in that case.
Regards,
Roland
