    Description

      If you pre-split a brand new collection into a large number of chunks, it will take a long time for the balancer to balance out those new chunks, because only one chunk is moved every few seconds. If there's no actual data to move, chunk migration is really just a metadata update to the config database, and should be able to be done instantaneously.
