             Summary: [cache store] Add valid flag in table wrapper for all 
constraint 
                 Key: HIVE-24344
                 URL: https://issues.apache.org/jira/browse/HIVE-24344
             Project: Hive
          Issue Type: Task
            Reporter: Ashish Sharma
            Assignee: Ashish Sharma


Description

Currently if get null for a constraint value we fall back to raw store to 
validate weather NULL is correct or not. We can add a valid flag which states 
that NULL constraint value is correct and thus reduce raw store call.

DOD
Add flag for all 6 constraint in cachedstore
