Zhong Yanghong commented on KYLIN-3694:
---------------------------------------
Hi [~kangkaisen], I have a few questions:
* Cube building
** Since the data stored in Druid is not encoded, do we really need Kylin
Dictionaries in this case? Is there any benchmark for using dictionary or not
using during cube building?
** For cuboid id, it's now regarded as a specified column. Will it sacrifice
the flexibility of column order, column adding, column deletion...
** By the Convert to Druid step, will it produce too many small files? Is there
any step for merging small files?
