Summary: 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
Currently, instance-level details of fragment events are completely omitted
from the experimental profile 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.
