Question about normal cube merge streaming cube
Hi,
My group is looking for a way to concat a streaming cube (realtime data) with a normal cube (history data).May be it's about the button "merge" in visable interface ,but I found it cann't work as "merge" only supports cubes in the same model and they need to be from the same source like table "table" basicly.
In the other side, someone suggect to use system with flink to make it complie.
So may you give me a suggest,whether there is a way to solve this problem in kylin or I should turn to system with flink?
Thanks,
William

There is no Chinese version of this document at present.
You should only be able to read the English version in a short time. hahaha

Hi：
Maybe you can try lambda mode in kylin real-time, which supports adding history table and real-time data source in a model.
