Hi, I am trying to understand kylin 1.5.3 query logic, but I found it
is much more difficult to understand than kylin 1.2, mainly because of
introduce of gridtable, so I want to ask why gridtable is introduced?

Hi:
Does kylin support multiple user besides ADMIN?
This may be useful when integrating kylin in our workflow, we may need to

Thanks.
