[jira] [Created] (IMPALA-5888) Parquet scanner does not free local allocations for min/max and dictionary filters

Tim Armstrong created IMPALA-5888:
-------------------------------------

             Summary: Parquet scanner does not free local allocations for min/max and dictionary filters
                 Key: IMPALA-5888
                 URL: https://issues.apache.org/jira/browse/IMPALA-5888
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.9.0, Impala 2.10.0
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


This is the same issues as IMPALA-5885, but for the other conjuncts. I think min/max conjuncts are unlikely to be problematic now since they're evaluated once per row group, but we could accumulate a lot of memory from dictionary conjuncts.
