> Key: IMPALA-6957
> URL: https://issues.apache.org/jira/browse/IMPALA-6957
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Not Applicable
> Reporter: Tim Armstrong
> Assignee: Tim Armstrong
> Priority: Major
> Labels: resource-management
> Fix For: Impala 2.13.0, Impala 3.1.0
>
>
> Impala has an internal notion of "required threads" to execute a fragment,
> e.g. the fragment execution thread and the first scanner thread. It's
> possible to compute the number of required threads per fragment instance
> based on the plan.
> We should include this in the resource profile and expose it in the explain
> plan. This could then be a step toward implementing something like
> IMPALA-6035.
