>            Priority: Major
> 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
