          The maximum number of documents in each batch to delete during the cleanup stage of chunk
          migration (or the cleanupOrphaned command). The default value of 0 indicates that the

        description: >-
          The maximum number of documents to insert in a single batch during the cloning step of
          the migration process. The default value of 0 indicates no maximum number of documents
          per batch. However, in practice, this results in batches that contain up to 16 MB of
          documents. The value 1 corresponds to MongoDB 3.4.16 (and earlier) behavior.
