----------------------------------------

             Summary: optimize presto query time for dictionary include string column
                 Key: CARBONDATA-3237
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-3237
             Project: CarbonData
          Issue Type: Bug
            Reporter: Ajantha Bhat
            Assignee: Ajantha Bhat


optimize presto query time for dictionary include string column.

 

problem: currently, for each query, presto carbon creates dictionary block for string columns.

This happens for each query and if cardinality is more , it takes more time to build. This is not required. we can lookup using normal dictionary lookup.
