----------------------------------
What will be the problem if applied to the production environment (except for
the large profile)
We also do not apply to insert operations.
> Experimental flag for running all queries with mt_dop

> Key: IMPALA-8097
> URL: https://issues.apache.org/jira/browse/IMPALA-8097
> Project: IMPALA
> Issue Type: Sub-task
> Components: Distributed Exec
> Reporter: Tim Armstrong
> Assignee: Tim Armstrong
> Priority: Major
> Fix For: Impala 3.3.0
>
>
> It's possible to execute queries with joins and inserts with mt_dop with some
> small modifications to the Impala code (without the separate join build
> work). This isn't production-ready because of the other subtasks of
> IMPALA-3902 but it would be useful to have an experimental flag for people to
> play around with to test the functionality.
