      Currently mognoexport and mogodump use a single find query per collection. We could use the mongosync partitioning logic to run multiple queries in parallel per collection.

      Acceptance criteria:

      • Test the performance impact of running multiple queries in parallel to copy data.
      • If the test shows good results, add parallel queries to mongoexport and mongodump. Also:
        • Consider adding an option to change the number of parallel queries per collection
        • This is particularly important for mongoimport since if the --sort option is set, then we cannot use parallel queries.
