Hi, all
In reality, some small modify may be add into existing cube(like add a new
measure),I search for some infomations that we could clone a new cube, but
in this way, we must also rebuild all history data in new cube, or we can't
query the sql in which part_date includes old and new values.

For example,kylin_sales_cube(partition start form 2012-01-01) build from
2012-01-01 to 2012-06-01 
and 
kylin_sales_cube_clone(partition start form 2012-09-01) build from
2012-09-01 to 2012-12-01

from now on,we want to stop incremental build for the formmer but change to
build the latter one.(since more and more cube will hard to manager and take
more compute and storage resource?)

sql:select part_dt, sum(price) as total_selled, count(distinct seller_id) as
sellers from kylin_sales where part_dt > '2012-01-01'  group by part_dt
order by part_dt;

only show up statistic from kylin_sales_cube

How can we make the sql show all data(merge result of 2012-01-01~2012-06-01
and 2012-09-01~2012-12-01) without rebuild all history segment?



Thanks a lot.
