Hi,
I have some questions about how Kylin refresh dimensions tables. In case you delete some instances of the dimension on hive table that are not used by any fact in fact table, These values will be deleted from dimension table on next cube segment built? We have to refresh old segments? In our case we have added by mistake a lot of empty future days to a Date dimension (80 years). Then we have built some days of the cube. However, as this big date dimensions leads to performance issues, we have deleted most of future years from Date dimension. However, after built a new segment of the cube, the deleted rows on Hive table they have not been deleted in Kylin cube table. How can we refresh the dimension table on Kylin properly? Thanks in advance!
