             Summary: More intelligent selection of parallelism in non-scan fragments.
                 Key: IMPALA-9808
                 URL: https://issues.apache.org/jira/browse/IMPALA-9808
             Project: IMPALA
          Issue Type: Improvement
          Components: Perf Investigation
            Reporter: Tim Armstrong


We currently choose the parallelism of interior fragments based on the parallelism of the scans. This is a placeholder to re-evaluate this decision. It's unclear what direction this should go in - t really needs investigation
