We planned all the operation without the virtual clock (used in all labs), should we modify the approach to include its use?

We can discuss about this but, for now, the idea of "ordering" I was thinking was only related to the concept of "who requested what" and my first try was to sort of "encapsulate" messages on the way up, to preserve the information about the client and key, and then about the caches.

like the following:

public class ClientReadRequestMsg implements Serializable {

    public final int key;
    public final ActorRef client; //this or clientID?

    public ClientReadRequestMsg(int key, ActorRef client) {
        this.key = key;
        this.client = client;
    }
}

public class CacheReadRequestMsg implements Serializable {

    public final int key;
    public final ActorRef cache; //this or cacheID?
    public final ActorRef client;
    
    public CacheReadRequestMsg(ClientReadRequestMsg clientMsg, ActorRef cache) {
        this.key = clientMsg.key;
        this.cache = cache;
        this.client = clientMsg.client;
    }

    public CacheReadRequestMsg(CacheReadRequestMsg cacheMsg, ActorRef cache) {
        this.client = cacheMsg.client;
        this.cache = cache;
        this.key = cacheMsg.key;
    }
}

I'm developing the approach and still trying to figure out if it will work
