    _logger.info("data size : "+saleData.size);

    saleData.parallelStream().forEach(data -> {
                SaleAggrData saleAggrData = new SaleAggrData() {
                    {
                        setCatId(data.getCatId());
                        setRevenue(RoundUpUtil.roundUpDouble(data.getRevenue()));
                        setMargin(RoundUpUtil.roundUpDouble(data.getMargin()));
                        setUnits(data.getUnits());
                        setMarginRate(ComputeUtil.marginRate(data.getRevenue(), data.getMargin()));
                        setOtd(ComputeUtil.OTD(data.getRevenue(), data.getUnits()));
                        setSaleDate(data.getSaleDate());
                        setDiscountDepth(ComputeUtil.discountDepth(data.getRegularPrice(), data.getRevenue()));
                        setTransactions(data.getTransactions());
                        setUpt(ComputeUtil.UPT(data.getUnits(), data.getTransactions()));
                    }
                };
                salesAggrData.addSaleAggrData(saleAggrData);
            });

代码的问题是当我从DB获得响应时,并且在使用并行流进行迭代时,每次数据大小都不同,而使用顺序流时,它工作正常.

我不能使用顺序Stream因为数据很大并且需要时间.

任何领导都会有所帮助.
