Zhong Yanghong updated KYLIN-3362:
----------------------------------
Description:
Here, dynamic dimension is mainly for {{case when}}. By push down, the
cardinality will be reduced and the returned result row number can be reduced.
For simplicity, if columns exist in {{then}}, currently we don't do the push
down.
The same as [KYLIN-3359], the related filters in case when have to be able to
be pushed down.
