> Key: IMPALA-13714
> URL: https://issues.apache.org/jira/browse/IMPALA-13714
> Project: IMPALA
> Issue Type: New Feature
> Reporter: Surya Hebbar
> Assignee: Surya Hebbar
> Priority: Major
>
> Across aggregated plan nodes' event sequences, while producing the JSON form
> for a particular query, it is possible to identify slow instances.
> During aggregation for the JSON profile, we can use a map with instance name
> as the key and count the number of times a particular instance comes last.
> There is a need to define and refine which ones would be the slow instance,
> but this is the general idea.
