[jira] [Created] (IMPALA-12387) PartialUpdates is misleading for LOCAL filter

Riza Suminto created IMPALA-12387:
-------------------------------------

             Summary: PartialUpdates is misleading for LOCAL filter
                 Key: IMPALA-12387
                 URL: https://issues.apache.org/jira/browse/IMPALA-12387
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 4.2.0
            Reporter: Riza Suminto


In filter table, PartialUpdates is intended to mark if coordinator receive only partial update for a MIN_MAX filter from contributing fragments. This can be misleading for LOCAL filter because LOCAL filter does not aggregate in coordinator. Thus, coordinator does not receive any filter update.
