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. was:Here, dynamic dimension is mainly for case when for column.
