Summary: Segment pruning based on partition column's hierarchies
Key: KYLIN-1150

Project: Kylin

Reporter: hongbin ma
Assignee: hongbin ma
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
