             Summary: Segment pruning based on partition column's hierarchies
                 Key: KYLIN-1150
                 URL: https://issues.apache.org/jira/browse/KYLIN-1150
             Project: Kylin
          Issue Type: Improvement

current query engine will prune segments if the query has filters on partition column. In many cases, partition columns comes with hierarchies. for example if the partition column is daystart, it may come with monthstart,yearstart columns. Filters on monthstart,yearstart  should also help to prune segments
