Performance tips for LiveData in Android?

        // Example of LiveData usage
        public class MyViewModel extends ViewModel {
            private final MutableLiveData userLiveData = new MutableLiveData<>();

            // Method to get LiveData
            public LiveData getUser() {
                return userLiveData;
            }

            // Method to fetch data
            public void fetchData() {
                // Simulate data fetch from a repository
                User user = repository.getUserFromDatabase();
                userLiveData.postValue(user);
            }
        }
