android - Do we need to use background thread for retrieving data using firebase?

Question

I've an android app where I'm retrieving data into a Fragment. And I believe that Firebase manages its asynchronous calls. But still I've doubt the if we need to write the Firebase code in the background thread or not?.

If we need to write it into the background thread then can you please tell which operations takes more time. eg:

mDatabase = FirebaseDatabase.getInstance().getReference().child("Blog");

I think that performing this on the main UI thread may become risk full because setting connection between database may sometime take large time.
