[ https://issues.apache.org/jira/browse/KYLIN-4908?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
ShengJun Zheng updated KYLIN-4908:
----------------------------------
Description:
1. It's allowed to use int/bigint partition column from hive table to divide KYLIN's segments, but segment pruner doesn't support prune segments based on integer-type partition.
2. For String type of partition column (string date_str), date_str = '20210221' will trigger partition pruner, date_str = 20210221 will not
