Writing and composing the file itself takes some time. IMO, if it involves a large amount of data (more than 500,000 or above), there isn’t a better approach. Or does anyone else have a better idea? 写入和组成文件本身就需要一定的时间。我认为如果是大量数据(大于50万或以上),并没有更好的办法。或者其他人有更好的想法? |

大学生不是很理解,想来请教一下
对于高性能导出大量数据到Excel,各位一般如何处理的?之前接触到的是分批次读表+多线程增量写Excel类似这种思路方案,但是多线程自然就不方便控制导出顺序,想知道各位在处理大数据量顺序导出的时候,还有性能提高手段么?还是说就只能采用任务中心的方式,让用户稍微下载?
