----------------------------------
Summary: Enhance the support of trivial query admission
Key: IMPALA-11863
URL: https://issues.apache.org/jira/browse/IMPALA-11863
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: David Woo
As in IMPALA-7969, a query which meets the requirement of a trivial query, like
"select 1", could be admitted immediately to bypass the admission controller.
This task is to extend this functionality for a query when it is considered
small enough to bypass the admission controller and execute in the coordinator
without waiting to start a new executor when there is no available executor in
the current executor group.
The definition of the extended trivial query is to be discussed.
