             Summary: Add non nullability flag to druid time column
                 Key: HIVE-17871
                 URL: https://issues.apache.org/jira/browse/HIVE-17871
             Project: Hive
          Issue Type: Improvement
          Components: Druid integration
            Reporter: slim bouguerra


Druid time column is non null all the time.
Adding the non nullability flag will enable extra calcite goodness  like transforming 
{code} select count(`__time`) from table {code} to {code} select count(*) from table {code}
