-------------------------------------
Summary: Admission control accounting for mt_dop
Key: IMPALA-8998
URL: https://issues.apache.org/jira/browse/IMPALA-8998
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Tim Armstrong
Assignee: Tim Armstrong
We should account for the degree of parallelism that the query runs with on a
backend to avoid overadmitting too many parallel queries.
We could probably simply count the effective degree of parallelism (max #
instances of a fragment on that backend) toward the number of slots in
admission control (although slots are not enabled for the default group yet -
see IMPALA-8757).
