In the Lab: Building an Index in the Foreground in Production, the queries took longer time, after running building_index_in_foreground.py. Is it becuase during those operations are queried on mongo when index is being built? If so, i haven’t seen any of those operations going into the ‘qrw’ field in mongostat. If not so, when do operations go into the ‘qrw’?
please help me understand what happened there.
