Why we need gridtable?
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?

It's an abstraction of the cube storage; this makes cube build and query
code more clear and loose coupling.
