      Description

      Impala collects some stats related to dml execution. Currently, these are reported back to the coordinator (in a DmlExecStatusPB) only with the final status report, as its tricky to report them in an idempotent way.

      With IMPALA-4555, we're introducing functionality for portions of the status report to be non-idempotent. We can use this mechanism to report the dml stats incrementally during query execution, instead of once at the end, which is useful for user visibility into the status of running queries.
