[jira] [Created] (CARBONDATA-2343) Improper filter resolver cause more filter scan on data that could be skipped

xuchuanyin created CARBONDATA-2343:
--------------------------------------

             Summary: Improper filter resolver cause more filter scan on data that could be skipped
                 Key: CARBONDATA-2343
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2343
             Project: CarbonData
          Issue Type: Bug
          Components: data-query
            Reporter: xuchuanyin
            Assignee: xuchuanyin


In DataMapChooser, Carbondata try to choose and combine datamap for expressions. In some scenario, it will generate `TrueConditionalResolverImpl` to wrap the sub-expression, which will cause data scan on the blocklet which can be skipped (For `TrueConditionalResolverImpl`, the  `TrueFilterExecutor` will always cause scanning the data even it simply wraps a range expression).
