[jira] [Created] (IMPALA-6131) Track time of last statistics update in metadata

Lars Volker created IMPALA-6131:
-----------------------------------

             Summary: Track time of last statistics update in metadata
                 Key: IMPALA-6131
                 URL: https://issues.apache.org/jira/browse/IMPALA-6131
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: Lars Volker


Currently we (ab-)use {{transient_lastDdlTime}} to track the last update time of statistics. Instead we should introduce a separate counter to track the last update. With that we should also remove all manual updates to {{transient_lastDdlTime}} from {{CatalogOpExecutor}} and fall back to Hive's default behavior.
