             Summary: LLAP: better column vector object pools
                 Key: HIVE-12227
                 URL: https://issues.apache.org/jira/browse/HIVE-12227
             Project: Hive
          Issue Type: Bug
            Reporter: Gopal V
            Assignee: Sergey Shelukhin


Vector allocations become a problem in sub-second cases. The pool of 8 per 
request is too small. Needs to be bigger and potentially pre-populated if we 
can do it off the main path.
