[jira] [Created] (IMPALA-6875) Reservations for ORC scanner

Tim Armstrong created IMPALA-6875:
-------------------------------------

             Summary: Reservations for ORC scanner
                 Key: IMPALA-6875
                 URL: https://issues.apache.org/jira/browse/IMPALA-6875
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


This tracks the work needed to get ORC to be a first-class citizen when it comes to scanner reservations, i.e. reserving the memory required for holding columns in memory instead of just mallocing.
