Hi Dongpeng,

For most data warehouse system, the data is read only, and will not update
frequently. Kylin supports reload the history data by refreshing the
segments For the frequency updates historical data, you could isolate them
into samller segments. This works for the historical data changes.

If the table structure changed, you have to define new model or cube to fit
with new structure.
