Subject Re: Diff between build and refresh
Date Mon, 01 Jul 2019 02:54:53 GMT
Hi ning, 
   As far as I can see, Refresh action will check if you have a exist segment meet segment
range for which you request, but Build action won't do such check. So if you really want to
fresh (not create a new one), use refresh will be better/safe beacuse it won't mess up if
you do mistake in typing segment range.

如果按天分区,20190601这一天的cube已经build,那我再次build和refresh会有什么区别吗,我自己测试发现,如果重复build,应该会吧旧的数据给覆盖掉,那岂不是build和refresh是一样的了吗?
