----------------------------------------------
Summary: 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
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.
