      Parameters:
      projectionType - projection type
      Returns:
      a new QuerydslDataFetcher.Builder instance with all previously configured options and projectionType applied

      By default, this is OffsetScrollPosition.initial() with a count of 20.

      Returns:
      a new QuerydslDataFetcher.Builder instance with all previously configured options and Sort applied
