> Some performer implementation requires watch a file directory for file events like CREATE, UPDATE and DELETE.
> If each performer implements its own Watch Service, it means that each one will have an additional thread for watching the directory which would be a waste of resources in most cases, since Fey could have one only thread that watches all necessary directories for all running performers and send a message to the performer once it receives the event that the performer is looking for.
> *Suggestion:*
> Fey will implement its own *Global Watch Service* and will be responsible for keeping it running and distribute the events to the right Performers.
> In order to use it, the performer will have to send a message to the Global Watch Service Actor on Fey that contains:
> * ActorRef
> * Directory Path
> * Optional File name (In case it is watching for changes on a specific file)
> * List of Watch Events that it is waiting for
> The FeyGenericActor will offer a new method that would be called every time the Performer receives a new event. It would contain:
> * Path
> * Event type
> {code}
> This approach will require changes on FeyGenericActor.
> All performers will have to be updated.
> {code}
