Actors are about distribution and about encapsulating state that can be safely accessed concurrently. There are situations where one could choose to put all the code that accesses the DB to an actor so access to DB is only from a one thread at a time, but that is a very specific requirement. > if the answer is yes - is it a good practice to send the repository to > actor ? or is it better use dependency injection > When sending dependencies in a message you need to make sure that your actor does not start handling business messages until dependencies are sent in.
