                 Key: CARBONDATA-3974
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-3974
             Project: CarbonData
          Issue Type: Bug
            Reporter: Ajantha Bhat
            Assignee: Ajantha Bhat


a)  For 200K segments table in cloud, presto partition query was taking more than 5 hours. the reason is it was reading all segment files for partition pruning. Now it is less than a minute !

 

b) If the query filter is less than or greater than or more than one value. Partition pruning is not working in presto (due to missing code in presto-carbon integration)
