        var rowAccounting = new RowCellsAccountingWithEstimators(leftSideColumnTypes, ramAccounting, 0);
        return new CrossJoinBlockNLBatchIterator(left, right, combiner, blockSizeCalculator, rowAccounting);
    } else {
        return new CrossJoinNLBatchIterator<>(left, right, combiner);
    }
