Hi, I am new to Akka and I am reading the "Getting Started Guide".
In the part 5 of the tutorial (https://doc.akka.io/docs/akka/current/guide/tutorial_5.html) we can find the following paragraph: "One approach for implementing the query involves adding code to the group device actor. However, in practice this can be very cumbersome and error prone. Remember that when we start a query, we need to take a snapshot of the devices present and start a timer so that we can enforce the deadline. In the meantime, *another query* can arrive. For the second query, of course, we need to keep track of the exact same information but in isolation from the previous query. This would require us to maintain separate mappings between queries and device actors." I think it gives good reasons why not to implement the query in the DeviceGroupActor, but I also think that it missed a more important reason: messages are not processed in parallel by a given actor instance, so if a query is being executed by a DeviceGroupActor and a new query arrives, the new query will have to wait for the first one to be finished. Still on this paragraph I think "device group actor" would be preferable to "group device actor".
