Let me answer this in Chinese since a similar question has been answered in English.
麒麟Cube有Segment的概念，每个Segement对应一段时间。每次Build其实都是构建一段时间的Segment（这里假设Cube在创建时设置为Partitioned，并且设置了时间字段）。所以当数据变化，只需要刷新对应的Segment就可以了。 对于很古老的不再会更新的Segment，可以多个Segment合并起来，一般保持在一个月或者几个月一个Segment，这样总体的性能会比较好。 On Thu, Jan 7, 2016 at 11:10 AM, wenye...@163.com <wenye...@163.com> wrote: > > Thank you for your reply to my question, but my question is my original > data has increased, so the amount of data cube how automatically to > increase.
