-------------------------------------
Summary: Include number of required threads in explain plan
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
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.
