最近接了个项目, 感觉需求方不是很成熟, 但是做着做着发现自己也不是想象中那么成熟, 发现了自己的很多问题, 每每想到这样不是很舒畅 。
1. 要改改自己的工作风格阿 , 不能每次都让压力最后都放到自己这边来, 有什么可以预料的还是坚持去先做吧, 有时候是自己,有时候是别人以为那是一件比较简单的事情, 但是做起来却不是这样, 或者之前因为了解的不够深, 不知道这件事情到难度。难道这个就是产品经理要做的事情: 过滤分析需求, 跟需求方“讨价还价”, 真正针对需求而不是你或者他一个人说了算到事情? more to learn~
2. 任何一件大的任务, 其实没必要想一口吃了这个大西瓜, 可以慢慢的一口口吃, 说不定会有意外的收获。 这次的实战经历是导数据, 6百多万的数据。。。。其实每次如果10w的话, 写个脚本也就60次的重复工作而已, 但是每次的数量级以及需要的资源就降了一个很大到数量级了。。。
3. 用python处理大数据量的效率实在不敢恭维, 虽然python在其他方面很出色 , 但是有gc的语言难免会有这样的问题。
相反这次用shell脚本处理就比较快了, sed和awk还是非常强大的。还有非常感谢自己的mac, 4G的内存在关键时候派上了用场! 哈哈~
4. 还是想多了解一点mysql的index的相关知识。
5. more to complete~(记得再补充了)
