Tim Armstrong updated IMPALA-8139:
----------------------------------
Priority: Minor (was: Major)
> Report DML stats incrementally
> ------------------------------
>
> Key: IMPALA-8139
> URL: https://issues.apache.org/jira/browse/IMPALA-8139
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend, Distributed Exec
> Affects Versions: Impala 3.2.0
> Reporter: Thomas Tauber-Marshall
> Priority: Minor
>
> 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.
