[jira] [Created] (IMPALA-9155) Single Admission Controller per Cluster

Lars Volker created IMPALA-9155:
-----------------------------------

             Summary: Single Admission Controller per Cluster
                 Key: IMPALA-9155
                 URL: https://issues.apache.org/jira/browse/IMPALA-9155
             Project: IMPALA
          Issue Type: New Feature
          Components: Backend
    Affects Versions: Impala 3.4.0
            Reporter: Lars Volker
            Assignee: Lars Volker


We should consider building a single admission control service that can admit queries for multiple coordinators. This would simplify the current approach where coordinators make distributed decisions, remove the risk of overadmission by concurrent decisions, and allow us to implement more sophisticated admission control strategies.
