      Description

      SERVER-27725 implemented batch inserts for chunk migrations, but for some workloads inserting a ~16MB batch can impact secondary read performance. This ticket would be to implement a tuneable parameter to control how many documents were inserted using the batch insert rather than inserting the entire batch at once.
