      Secondary nodes can show replication lag when we for example a bulk collection create and index build operation is run on a very large number of small collections.

      Observed as an issue in HELP-56561, this is due to our inability to parallelize these operations.  Leaving this ticket to reference as a known issue, and possibly look into what kinds of mitigation could be done for this.
