> Include aggregate instance-level metrics within experimental profile(V2)

> Key: IMPALA-13304
> URL: https://issues.apache.org/jira/browse/IMPALA-13304
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Surya Hebbar
> Assignee: Surya Hebbar
> Priority: Major
>
> Currently, instance-level details of fragment events are completely omitted
> from the experimental profile(V2) in contrast with the traditional profile.
> This is to stop the profile size from blowing up with increasing number of
> nodes.
> Due to this, the query timeline's fragment timing diagram does not function.
> The generated profiles can be switched by setting
> {{gen_experimental_profile}} to {{true}} or {{{}false{}}}.
> It would be beneficial to include aggregate instance-level metrics without
> blowing up the profile size in case of large number of nodes. This would
> further help in plotting the query timeline's fragment timing diagram as well.
