Date Thu, 03 Nov 2016 16:01:03 GMT

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

             Summary: Dictionary cache not getting cleared after task completion in dictionary
decoder
                 Key: CARBONDATA-375
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-375
             Project: CarbonData
          Issue Type: Bug
            Reporter: Manish Gupta
            Assignee: Manish Gupta
            Priority: Minor
             Fix For: 0.2.0-incubating


Currently LRU cache eviction policy is based on dictionary access count. For cache to remove
a entry its access count must be 0. In dictionary decoder after conversion of surrogate key
to actual value the access count for dictionary columns in query is not getting decremented
due to which it will never be cleared from memory when LRU cache size is configured.
